Weigh the loaded rig, hook coupler and crossed chains, test brakes and lights, write both tire numbers, and park on blocks on the reserved pad.

Key takeaways

  • The door sticker is the truck.
  • Pin, chains, breakaway, lights.
  • Write both psi numbers.
  • Level on the pad.

RV towing is a hitch you can name, a weight that is under the door sticker, and a walk-around you do every time — not a hope and a YouTube yank. The short answer: match the trailer to the tow vehicle, set the coupler and chains like you mean it, and stop if the mirrors, brakes, or sway say no.

Short version. Where you store the rig is the off-season half. Park pads want a length you reserved. Pair with trailer habits if the other Saturday is a boat. Check live prices.

This page is the tow. A generator page is a different job. A golf-cart cover is not a hitch.

Coupler, chains, and a walk-around. The turnout is where you find the miss, not the interstate.

Match the trailer to the truck before you buy a weekend

The door sticker is the law of the truck. Tongue weight, GCWR, hitch class. A travel trailer that “looks light” and sits on the ball like a diving board is a sway you will meet at 62. Weigh the loaded rig once. A bathroom scale under the tongue is a rumor. A CAT scale is a number.

Do: a weight-distribution hitch when the maker says so. Don’t: a ball that is the wrong diameter, a drop that puts the trailer high in the back, or a rental truck you have not measured. First-time mistakes scale to a trailer. The dealer will still sell you a floorplan that is too much truck. That is not their test.

Hook like a person who will still have a trailer at the next exit

Coupler locked. Pin in. Chains crossed under the tongue so a dropped coupler rides the X, not the asphalt. Breakaway cable attached to the truck, not to a chain that will leave with the trailer. Lights: running, brake, turn. A helper calling “good” from the sofa is not a walk-around.

Mirrors that see the last six feet of the trailer are the mirrors you need. Clip-ons if the stock glass is a postcard. Trailer maintenance is bearings, lights, and a tire that is not a ten-year crack. Do the walk every time. Don’t skip it because you “just unhooked for lunch.”

Tires and brakes are the tow you cannot talk past

Trailer tires and truck tires are different numbers. Write both. Cold. The AstroAI Heavy Duty stick is the live gauge we named: 0–230, a head you can still read with gloves. Check live prices.

Don’t guess “about right.” A trailer tire that looks fine and is 20 psi low is a blowout at an on-ramp. Do: a brake-controller setting you tested in an empty lot, not on I-40. Don’t: a controller you never touched after the installer left.

Level on the pad, not on a living root

The Camco Heavy Duty 10-pack is the live block set we named: stack to a height, a bag, a job that matches a park pad. Do not stack a tower on soft dirt off the pad. Check live prices.

Chock before you unhitch. A slide that hits a tree is a slide you pay for. Walk the envelope. The TV can wait until the rig is not a rollaway. Don’t dump on the pad. Don’t generator at 6 a.m. if the sign says 8.

Drive like the trailer is a second vehicle you cannot see

More space. Earlier brakes. No sudden lane changes in a crosswind. A mountain descent is a gear, not a riding the pedal until the smell starts. If sway starts, a light brake on the trailer — not a yank on the wheel — is the first move a lot of controllers are for. Practice in an empty lot. Winter roads if the Saturday is already ice.

Fuel: you are heavier. Stops take longer. A “I can make it” on a mountain grade is how people cook a transmission. Don’t pass on a two-lane because the car behind is impatient. Do: a turnout when the line is a parade.

The tow is a sticker, a pin, two psi numbers, and a pad

Weigh it. Hook it. Write the air. Level on the pad you reserved. Check live prices. The weekend starts when the walk-around is boring.

Empty-lot practice is the tow you cannot skip

A grocery lot at dawn is where you learn the swing. Back toward the driver’s side if that is the side you can see. A spotter you can hear. One word for stop. If you cannot see the hitch, you do not guess — you get out. Boat-trailer habits are the same geometry with a different hull. A campsite that is a one-way loop is not the place you invent a 90-degree first time.

Do: cones or bags as a gate. Don’t: a Sunday afternoon in a busy lot with a 32-foot that still feels new. Fuel stops take longer. You are heavier. A “I can make it” on a mountain grade is how people cook a transmission. Plan the next diesel before the last one is a light.

Wind on a high-profile trailer is a lane you hold, not a lane you fight. A light trailer-brake tap is the first move a lot of controllers exist for. Practice that in the empty lot too. Winter roads if the Saturday is already ice. Check live prices on the gauge and the blocks. The lot is cheaper than a claim.

A CAT scale is a number you write on a card

Steer, drive, trailer. Three tickets. Tongue is a math you can do once. A brochure weight is a dry floorplan. Water, gear, and the dog are the real tongue. If the rear of the truck is already squatting in the driveway, you wanted distribution or a smaller box. Park pads still want a length you reserved. A scale will not invent a longer pad.

Do: weigh after you load the way you travel. Don’t: weigh empty and add “about 800.” Axle ratings are not a vibe. A tire that is legal and overloaded is a blowout you will meet at an on-ramp. Write truck and trailer psi cold. The AstroAI-class stick is how you know you did not invent 80.

Hitch class on the receiver is a stamp. A 2-inch ball that is the wrong diameter is a coupler that can leave. Confirm. A pin that is a bolt from a jar is a pin that will walk. Use the pin that came with the lock. Bearings and lights are the other number. Check live prices.

Night tows are a graduate course

If you cannot back the site in daylight, a lamp will not invent a better pad. It will show you the same tree with glare. Arrive with margin. A 10 p.m. full hookup in a new park is how people clip a slide. The TV can wait until the walk-around is boring.

Do: a headlamp in the same pocket every time. Don’t: a phone in your teeth on a tongue. White in a helper’s eyes is how people step off a pad. Red if someone is already in a neighboring slide. Generator hours still exist at 10 p.m. A whisper unit is still a neighbor if the sign says 8.

Ice and a grade are a gear and a longer gap. Winter road trips if the Saturday is already a front. Chains if the sign says chains. A trailer that is a sail on a ridge is a turnout you take. Check live prices. The weekend starts when the walk-around is boring.

The off-season is still a tow

Where you store the rig is a pad that is level, a cover that does not pond, and a battery you will maintain. Mice eat wiring. Empty the granola. A block stack that sits all winter on dirt is a stack that sinks. Level on something that will still be there in March.

Do: a last walk of lights and a controller you will not forget in a drawer. Don’t: a hitch you leave on the ball all winter in a puddle. The tow vehicle still wants oil and a tire you wrote. The trailer is not the only machine in the pair.

Insurance is a policy you can name. A handshake lot is not. Write who can move it. A coupler lock if the street is the lot. Check live prices on the blocks you will leave under the frame. The spring trip starts with a walk you already know.

Guests will try to write your day

A faster driver behind you is not a better driver. A line of cars is a turnout, not a reason to pass on a two-lane. Say the turnaround time at the house. If the answer is laughter, you are allowed to sit in the shade and wait for a kinder hour. That is a successful tow.

Kids belong in belts, not on a tongue in motion. A photo can wait until the wheels stop. A family loop can be the camp after the hitch is boring. Don’t a slide party until the chocks are in.

Closer: sticker, pin, two psi numbers, a pad, an empty-lot hour. Camco-class blocks on the reserved pad. A gauge you believe. Check live prices. The interstate is not the classroom.

The controller is a setting you test, not a story

A brake controller that is still on “default” is a controller you have not met. Test in an empty lot: a firm pedal should grab the trailer before the truck dives. Too little and the trailer pushes. Too much and you will smell the magnets on the first grade. Write the number you liked on a tape under the dash. Recheck when the load changes — water in the tanks is a different trailer.

Breakaway: pull the pin on purpose once a year in a safe lot and confirm the trailer brakes lock. Then reset. A cable that is clipped to a chain that will leave with the trailer is a cable that will not do its job. Attach it to the truck. Magnets and shoes wear. A 10-year-old brake that has never been adjusted is a 10-year-old surprise.

Lights: a helper at the back, not a “I saw them in the glass.” Running, brake, both turns, night markers. A cheap tester is allowed. A hope is not. Check live prices. The walk is the tow. The lot is cheaper than a claim. The weekend starts when this is boring.

Frequently asked questions

What is the first RV towing rule?

Match the loaded trailer to the truck’s door sticker — tongue, GCWR, hitch class — then weigh the rig once.

How should I hook up?

Lock the coupler, pin it, cross the chains under the tongue, attach the breakaway, and walk the lights every time.

What tire gauge should I buy?

The AstroAI Heavy Duty 0–230 stick. Write truck and trailer psi cold. Do not guess.

What leveling blocks?

Camco Heavy Duty interlocking blocks — a 10-pack. Level on the reserved pad, not a dirt tower.

What do I do if the trailer sways?

A light trailer-brake application and a calmer speed. Do not yank the wheel. Practice in an empty lot.

Can I skip the walk-around after lunch?

No. Coupler pins walk. Lights fail. The walk is the tow.
