Everyone's watching. Don't jackknife.
Back a boat, camper or cargo trailer down the ramp, into the driveway, or between the cones — with working mirrors, real hitch physics, and a crowd that is not on your side.
🚤 Coming soon to Google PlayBacking a trailer is the one driving skill nobody practices until they're doing it live — at the boat ramp, on a Saturday, with a line of trucks waiting behind them. Trailer Boss lets you get it wrong where it's safe. Real articulated hitch physics, a cockpit view with working side mirrors, and six jobs that ramp from an empty driveway to a packed launch. Miss the zone and the trailer jackknifes. Cut it too far and you'll clip a spectator who was, unfortunately, right there.
Straight down or angled back-in — square it in the zone and launch.
Back between the cars into the yard without a scratch.
Swing the trailer in along the kerb, level with the truck ahead.
Turn the rig around, then thread the fifth-wheel into the bay.
Back the camper into a tight campground slot between the posts.
Every job has a par time and a personal best to chase.
Swap between a boat, camper, cargo box, fifth-wheel and tandem trailer — and they don't drive the same. Short trailers dart and jackknife in a blink; long ones lag and track wide. The physics are the whole point.
A cockpit view with real, live side mirrors. Learn to read the mirror instead of the screen — the skill that actually transfers.
A deterministic articulated truck-and-trailer model. No arcade fudging — it behaves like the real rig on the real ramp.
Turn on the gallery and the ramp fills with spectators who watch, honk, and judge. Nerves are part of the skill now.
A steering guide and a no-rush Grandpa pace for first-timers. Expert turns the help off and lets you work it out.
Beat par on every job, then chase your own best time. Clean, fast, no touches — that's the run to beat.
Earn them the hard way. DOOR BASHER, PRETZEL, SUBMARINE, ICE WATER, RIG AGNOSTIC — some are compliments, some really aren't.
Anyone can back a trailer in an empty lot. Flip on Crowd Mode and the ramp fills with spectators, a honking line of trucks, and at least one crying baby. Clip one of them and you'll hear about it. It's the closest thing to real Saturday-morning boat-ramp pressure — without anyone remembering your name afterward.
Yes. The hitch physics are a real articulated model, so the muscle memory transfers — small corrections early, hand at the bottom of the wheel, watch the mirror the trailer drifts toward. Assist mode shows where to steer while you learn, and every mistake is free.
Put your hand at the bottom of the wheel and move it the way you want the trailer to go, correct small and early, and watch the mirror on the side it's drifting toward. Trailer Boss drills exactly this — with and without a crowd watching.
Yes — a deterministic articulated model with five trailer types that each behave differently. Short trailers dart and jackknife; long fifth-wheels lag and track wide, just like real life.
