First-Time Towing a Travel Trailer: The Complete Checklist

Do this before you are standing on a dealer lot with a trailer already attached, because it is the one question that cannot be fixed later with technique. Take the trailer's GVWR — not its dry, unladen or shipping weight — from the certification label on the forward half of the trailer's left side. Multiply by 13% for a conventional bumper-pull to get planning tongue weight. Add your passengers, everything going in the cab and bed, and the hitch hardware itself, which is around 90 lb for a weight distribution setup. Compare that total against the payload printed on the yellow tire and loading placard inside your driver's door. If the total is larger than the placard figure, no amount of careful driving fixes it. Ram's own towing basics document puts tongue weight at 10 to 15 percent of the trailer load with an ideal around 13 percent, which is where that multiplier comes from. Ford's guide gives the same instruction in checklist form: have the fully loaded vehicle, passengers included, and the trailer weighed, and if any limit is exceeded, remove cargo until the weights come back inside. Run the numbers through Can I Tow This?, then confirm them on a scale — the CAT scale guide covers the three-pass method.

If your tow vehicle is new, there is a good chance you are not supposed to tow with it yet — and the number depends on who made it. Ford states it plainly in the "Know Before You Tow" pages of its RV & Trailer Towing Guide: > do not tow a trailer until your vehicle has been driven at least 1,000 miles Ram publishes a different and stricter pair of figures in its towing basics document, framed as an engine break-in caution: > During the first 805 km (500 miles) a new vehicle is driven, do not tow a trailer. Doing so may damage the vehicle. > > Limit speed to (80 km/h) 50 mph during the first 805 km (500 miles) of towing. Note what that means: Ram asks for 500 miles before towing at all, and then a further 500 miles of towing at no more than 50 mph. Ford is stricter on the mileage and looser on the speed — 1,000 miles before towing at all, then 70 mph for the first 500 miles of towing. General Motors does not publish a figure in its trailering guide; it tells owners to follow the break-in and maintenance schedules in the owner's manual. The widely repeated "500 miles and 50 mph" rule is real, but it is Ram's, not a universal one, and quoting it at a new F-150 owner understates Ford's mileage by half. Ford separately gives 300 miles as a tyre break-in figure, which is a third number again and not a towing restriction. Check your own manual — this is the single most common place where forum advice is confidently wrong.

Handover day is rushed, and the walkthrough is usually about the fridge and the awning rather than the hitch. Take these in your own order. Get the numbers in writing. * The weight label on this specific unit, not the brochure. Every trailer is weighed at the factory and carries its own label. * The trailer's GVWR and its axle ratings. * What dealer-installed options were added after that label was printed, because they are not in it. Watch the hitch being set up, and take a photo of it. * If a weight distribution hitch is fitted, watch which chain link or socket angle the bars are set to, and photograph it. You will need to reproduce that setting. * Confirm the ball size stamped on the ball matches the size stamped on the coupler. * Confirm the safety chains are crossed under the coupler with only enough slack to turn. * Confirm the breakaway lanyard goes to a permanent part of the truck, not the ball or a chain loop. Test the brake controller before you leave the lot. Chevrolet's trailering safety checklist gives the method: with electric trailer brakes, test them by manually engaging the brake controller while the vehicle is moving slowly. You should feel the trailer tug the rig back. Set the gain properly rather than accepting whatever it was left at — the brake controller guide and the gain calculator cover it. Confirm the trailer battery is installed and charged. The breakaway switch does nothing without it. Run the full walk-around. Chevrolet publishes a compact version worth memorising: hitch and platform, hitch nuts and bolts, mirror adjustments, safety chains, vehicle and trailer lights, sway-control device fitted and working if one is required, tire pressure on both the tow vehicle and the trailer, brakes tested, breakaway connected and functioning, and all loads secure. The full hitching sequence, with the failure each step prevents, is in how to hitch a trailer.

Ford's towing guide opens its "Before Starting" advice with this, and it is the most-ignored line in the document: > Before setting out on a trip, practice turning, stopping and backing up your trailer in an area away from heavy traffic An empty retail car park on a Sunday morning is the classic venue. Twenty minutes there is worth more than any amount of reading. What to practise, in order: * Wide turns. The trailer's wheels cut inside the truck's path. Go further into an intersection than feels right before turning, or the trailer clips the kerb — and on a right turn, the kerb is where pedestrians stand. * Stopping distance. Get a feel for how much earlier you have to lift off. You are now stopping perhaps twice the mass with the same brakes plus whatever the trailer contributes. * Backing up. One hand at the bottom of the wheel, move it the way you want the trailer's rear to go. Small inputs, then straighten. Get out and look as often as you like. * Mirror coverage. Adjust so you can see the trailer's rear wheels and the lane beside it. If you cannot see down both sides of the trailer, you need extension mirrors before the trip, not after. Know your height and write it down. Ford's guide lists "know clearance required for trailer roof" as a pre-trip item. Measure from the ground to the highest fixed point — usually the air conditioner shroud — and put that number on a sticker on the dash. Every year people take the roof off a trailer at a drive-through or a low bridge, and the trailer's brochure height does not include what the dealer bolted on afterwards.

This is the section that separates a first trip that goes well from one that ends on a hard shoulder. Stop at about 50 miles. Ford's guide asks for it explicitly. Pull somewhere protected and re-check: * the trailer hitch attachment * the lights and electrical connections * the trailer wheel lug nuts for tightness * engine oil, and regularly through the trip Re-torque the lug nuts earlier than that on a new trailer. Jayco's warnings page is more aggressive than Ford's general advice, and it is the trailer maker's own instruction: > Check and re-torque lug nuts at 10 miles (16 Km), 25 miles (40 Km) and 50 miles (80 Km) and again periodically during travel. Jayco's travel checklist elsewhere in the same manual mentions checking lug nuts after the first two hundred miles, so the manual carries both figures — but the 10/25/50 schedule is the one on the safety-warnings page, and it is the one to follow on a new trailer or after any wheel has been off. Use a calibrated torque wrench in a star pattern and in two stages, not an impact gun. Jayco's own table runs 45 ft-lb then 70 ft-lb for 12" and 13" rims, and 65 ft-lb then 120 ft-lb for 14" through 17.5" rims. Check tire pressure cold, and know what "cold" means. Jayco defines it precisely: a tire that has not been used for three or more hours, or has been driven less than a mile. A hot tire can read as much as 6 psi above its cold pressure, so never bleed air out of a hot tire to hit the placard number — you will be badly under-inflated once it cools. Watch your speed against the tires, not just the signs. Special trailer (ST) tires carry a maximum speed of 65 mph. Exceeding a tire's speed rating risks failure regardless of what the posted limit says. At altitude, derate. Ford's guide asks owners to reduce GVW and GCW by 2% per 1,000 feet of elevation to match sea-level performance. On a 7,000-foot mountain pass that is a 14% reduction — worth knowing before you plan a summer trip through the Rockies at your maximum rating.

Dexter Axle supplies axles, brakes and hubs to much of the US trailer industry, and publishes a maintenance schedule that is more specific than most coachbuilder manuals. Worth setting reminders against on the day you take delivery. Two of those deserve special attention for a first-time owner. Wheel bearings get cleaned and repacked at 12 months or 12,000 miles — a service almost no new owner is told about, and a seized bearing at highway speed is a genuinely dangerous failure. And wheel nuts get re-torqued every 3 months or 3,000 miles, on top of the 10/25/50-mile schedule after any wheel comes off. One thing these sources do not give: a trailer tire replacement age. Neither Jayco's manual nor Dexter's schedule states a years-based limit, so treat the widely quoted "replace at three years" or "at five years" rules as opinions rather than manufacturer instructions, and inspect for cracking, bulging and uneven wear instead.

In rough order of how often they bite: * Planning against dry weight. The brochure figure is an empty trailer with no battery, no propane, no water and nothing you own. You tow the loaded weight. See dry weight vs GVWR. * Assuming tow rating is the limit. On most half-tons with a family aboard, payload runs out first. See payload vs towing capacity. * Too little tongue weight. Loading heavy behind the trailer axles to "balance" the hitch is how sway starts. Aim for 10–15% on the tongue, and see what causes trailer sway. * Breakaway lanyard on the ball mount. It leaves with the trailer in exactly the event it exists for. * Chains left long enough to drag. They wear through and are not there when needed. * Never testing the brake controller. A gain left at zero feels perfectly normal until the first hard stop. * Skipping the 50-mile stop, and with it the lug check. * Bleeding hot tires down to the placard pressure, then running badly under-inflated once they cool. * Towing a brand-new truck straight off the lot, before its break-in mileage. * Not knowing the trailer's height. The number belongs on the dash, not in the brochure. A printable version. There is a pre-trip checklist you can print and keep in the glovebox, plus a weight worksheet for the numbers from the first section. Doing it on paper the first half-dozen times builds the habit faster than trying to remember a list. One last piece of advice that comes up repeatedly from experienced owners and costs nothing: have the second driver in the household tow at least once, early, in the empty car park. If the only person who can move the rig is unwell or hurt three states from home, that is a much larger problem than a first lesson would have been.
