Why Demco's Integrated Braking Systems Beat Portable Units Every Time

Every flat tow setup needs a supplemental braking system on the toad (tow vehicle). It's the law in BC and in most of the US states snowbirds drive through on the way to Arizona, Palm Springs, or Mexico. More importantly, it's what keeps your toad from pushing your motorhome through a panic stop.

Once you're past the question of whether you need one, the next question is which one. Portable units and integrated systems both meet the law, both work, and we install both at our Chilliwack shop. So this isn't a story about which option is "wrong" — it's about what you get when you step up to the best system on the market.

After 30+ years and 500+ flat tow installs, Demco's two integrated options — the Stay-IN-Play Duo for hydraulic-brake motorhomes and the Air Force One for air-brake motorhomes — are what most of our customers end up with. Here's why.

What "Integrated" Actually Means

A quick definition before we get into the upsides.

Portable braking systems are box-shaped units that sit on the driver's side floor of the toad. You place the box, strap it in, plug it in, calibrate it, and connect the brake-pedal arm each time you hook up. They're a solid entry into flat towing and they meet the legal requirement.

Integrated braking systems are professionally installed once and live in the toad permanently. The components mount behind the dash, under the hood, and tie directly into the brake line. From then on, hooking up is just connecting the towbar and the wiring (or in the case of Air Force One, a single air line) — and you're ready to roll.

Same legal outcome. Very different experience.

Six Reasons Customers Step Up to Integrated

1. Hook Up and Go

This is the one most customers mention first. With an integrated system, there's no box to position, no straps to tighten, no brake-pedal arm to attach, no calibration before you pull out. You hook up the towbar, plug in the connector, and you're done. On a snowbird trip with multiple hookups between BC and Arizona, that saved time and hassle adds up fast — especially in cold mornings, parking lot rain, or after a long day of driving when you just want to get to the campsite.

2. True Proportional Braking

Demco's Stay-IN-Play Duo and Air Force One are both fully proportional. When you brake hard in the motorhome, the toad brakes hard. When you ease off, the toad eases off. The two vehicles slow down together, smoothly, as a single unit.

Proportional braking matters most in two situations: long downhill grades (think Coquihalla or the Cascade passes), where uneven braking will overheat your motorhome's brakes, and panic stops, where every metre of stopping distance counts. A proportional system gives you both.

3. Shorter Stopping Distances

Because the integrated system applies the toad's brakes instantly and in proportion to the motorhome, the whole rig stops faster. On a 30,000-pound motorhome with a 4,000-pound Jeep behind it, a few extra feet of stopping distance is the difference between a close call and a collision. Customers who switch from portable to integrated often tell us the first thing they notice is how much more confident the motorhome feels under braking — the toad isn't "pushing" them anymore.

4. Cleaner Cabin, More Storage

Integrated systems are invisible from the driver's seat. No box on the floor, no cables running to the brake pedal, no unit taking up storage space when you're not towing. The toad looks and drives like a normal vehicle, which matters more than you'd think when you arrive at a destination and want to drive into town for groceries.

5. Compliant Across Every Border You'll Cross

BC has its supplemental braking requirement. So do Washington, Oregon, California, Nevada, Arizona, and most other jurisdictions you drive through. Some states get specific about how the brakes have to apply, and a fully proportional integrated system meets the toughest version of those rules on every common route. If you're crossing the border every winter, that peace of mind is part of what you're buying.

6. Built to Live in the Vehicle, Not Travel With It

Demco's integrated components are designed to be mounted once and left in place. Nothing to set up, nothing to put away, nothing to forget at a campground. The Stay-IN-Play Duo is a sealed electronic system. The Air Force One uses your motorhome's own air pressure with no batteries or boxes to maintain. Both are engineered for the long haul — same performance on year five as on day one.

Stay-IN-Play Duo vs Air Force One — Which One Fits Your Rig?

Both are made by Demco. Both are proportional. The choice comes down to what kind of brakes your motorhome has.

Demco Stay-IN-Play Duo — For Hydraulic-Brake Motorhomes

Most Class A gas, Class B, and Class C motorhomes have hydraulic brakes. The Stay-IN-Play Duo installs in the toad and reads the motorhome's braking signal through the towbar wiring. When the motorhome brakes, the Duo applies the toad's brakes proportionally. When the motorhome releases, the Duo backs off — it "stays in play" with your braking input, smooth and continuous.

This is our most-installed flat tow braking system. Quiet, reliable, no maintenance routine, and it works the same on day one as it does five years later.

Demco Air Force One — For Air-Brake Motorhomes

Diesel pushers and larger Class A motorhomes use air brakes. Air Force One taps directly into the motorhome's air system through a single quick-connect line. When the motorhome's air brakes engage, the toad's brakes engage at the same pressure proportion in real time.

This is the gold standard for diesel pusher owners. The integration is so direct that there's no electronic translation, no lag, no calculation — air pressure in, brakes on. No batteries to replace. No control box on the floor. Just air.

Yes, Integrated Costs More Up Front

We won't pretend otherwise. The hardware is comparable in price to a portable unit, but there's professional installation labour to factor in. That's the honest tradeoff.

What customers tell us, looking back:

•       They use the brake system every single hookup — no skipping setup on "quick" trips

•       The system runs for the life of the toad with no maintenance routine

•       Dozens of hours saved over a few years of trips, not having to set up and tear down

•       Cleaner toad, higher resale value when they eventually sell it

•       More confidence on big downhill grades and panic stops

•       More reliable can’t get bumped or jarred out of place

Most of our integrated-system customers say the same thing after a year or two: they wish they'd gone integrated from day one.

Portable Systems Still Have Their Place

If integrated isn't the right fit right now — maybe you're only towing for a few short trips a year, your budget is tight this season, or you tow multiple vehicles and want to use one braking system for both — a portable unit is still a legitimate choice. They meet the law, they apply the brakes, and they're a solid way to get into flat towing without a bigger investment.

We stock and install portable systems too. If that's where you want to start, we'll set you up with one that fits your toad and walk you through it the same way we would with an integrated system. And when you're ready to step up later, the upgrade path is straightforward.

Frequently Asked Questions: Demco Integrated Braking Systems

Is a supplemental braking system actually required by law?

Yes. BC requires the towed vehicle to have its own braking system that engages with the motorhome's brakes if it’s over 4400lbs. or above 40% of the motor home's GVWR. Most US states you drive through — Washington, Oregon, California, Nevada, Arizona — have their own version of the same rule. Some apply it by weight, some apply it across the board. Whether you go integrated or portable, the safe answer for any cross-border RVer is: install one.

Stay-IN-Play Duo or Air Force One — how do I know which one I need?

It comes down to your motorhome's brake system. If your motorhome has hydraulic brakes (most Class A gas, Class B, and Class C motorhomes), you need the Stay-IN-Play Duo. If your motorhome has air brakes (most diesel pushers and larger Class A coaches), you need the Air Force One. If you're not sure which kind of brakes your motorhome has, call us with the year, make, and model — we'll figure it out for you.

How long does it take to install an integrated braking system?

The Stay-IN-Play Duo and Air Force One typically take a full day to install on the toad plus a half-day on the motorhome side. That’s on top of the baseplate and wiring install. In total the vehicle will be here for 2 days. We'll give you a firm timeline when we book the appointment.

Can I install it myself?

The hardware is available, but we don't recommend DIY for either system. Both tie directly into your toad's brake line — the Stay-IN-Play Duo into the hydraulic side, the Air Force One into the air system. Getting that wrong means the brakes don't work right when you need them most. Both manufacturers also want professional installation to maintain warranty coverage.

What does a complete integrated braking install cost?

Our standard Flat Tow Package includes a baseplate, towbar, braking system (Stay-IN-Play Duo or Air Force One), wiring, and toad protection. Some vehicles also need battery disconnects or ignition bypass switches — we'll confirm what your rig requires when you call. Give us the year, make, and model of both vehicles and we'll quote it straight.— no guessing, no "starting from" pricing that doesn't apply to your rig.

I already have a portable braking system. Can I switch to integrated?

Absolutely. We do these conversions regularly — customers who started with a portable unit, lived with the setup hassle for a season or two, and decided to upgrade. The portable unit comes out, the integrated system goes in, and the toad cabin is clean again. If your portable unit is in good shape, you may also be able to sell it used to recoup part of the upgrade cost.

Does an integrated system work on any vehicle?

It works on any vehicle that can be flat towed in the first place. The braking system doesn't change what's flat-tow capable — that's determined by your toad's drivetrain. If your vehicle is on the flat-tow-approved list (most Jeep Wranglers, Gladiators, 4WD Broncos, and some 4WD trucks with manual transfer cases), we can fit an integrated braking system to it.

Do I need to do anything to the system between trips?

Not really. Both Demco systems are designed to live in the vehicle permanently. The Stay-IN-Play Duo is a sealed electronic unit — no batteries to replace, no maintenance schedule. The Air Force One uses your motorhome's own air pressure, so there's nothing to charge or service. We recommend the same start-of-trip check you'd do with any braking system: at the first stop after you hook up, confirm the dash indicator shows the system is active and the vehicle's brakes are responding.

Will an integrated braking system void my vehicle warranty?

Installed correctly, no. The system ties into the brake line in a way that's designed to be reversible and doesn't modify the toad's stock components beyond the installation points. We've installed hundreds of these on vehicles still under manufacturer warranty without any warranty issues. That said, every manufacturer has their own policies, so if you're concerned, check with your dealer before booking.

Can I still tow if the integrated braking system fails?

Both Demco systems are designed to fail safe — if the system loses power or signal, your motorhome's own brakes still work normally, and the towed vehicle stays connected through the towbar. You wouldn't have supplemental braking until the system was repaired, which means you'd want to get it fixed before continuing a long trip. In 30+ years and 500+ installs we've had very few in-service failures on Demco's integrated systems — that's part of why we recommend them.
