Equal-i-zer Equal-i-zer 4-Point Sway Control Hitch, 90-00-1001

Equal-i-zer 4-Point Sway Control Hitch, 90-00-1001

Four-point sway control built into the head, so there is no friction bar to unclip before you back into a site — the single biggest quality-of-life difference for a first-timer.

TireMinder i10 RV TPMS with 4 Transmitters

Four transmitters and a dedicated monitor, which is exactly the count a tandem-axle travel trailer needs. The dedicated screen beats a phone app you have to keep awake.

LEXIVON LEXIVON 1/2 in Drive Click Torque Wrench, 25-250 ft-lb

LEXIVON 1/2 in Drive Click Torque Wrench, 25-250 ft-lb

Trailer wheels need re-torquing after the first 50 miles and periodically after. Guessing with a lug wrench is how wheels come off, and this covers the usual 90-120 ft-lb range.

Camco RV Wheel Chocks with Rope, 2-Pack

Two plastic chocks with a pull rope so you can retrieve them without lying on the ground. Unremarkable, correct, and the first thing to buy.

Milton S-986 Dual Head Tire Pressure Gauge, 10-160 psi

Trailer tires often run 50-80 psi, which is past the top of a typical car gauge. This one reads to 160 psi and the dual head reaches an inner dually valve.

The short answer

The five things people drive away still attached to: the power cord, the water hose, the sewer hose, the TV antenna (up), and the steps (out). Add the jacks still down and the awning still out, and that is most of the avoidable damage in trailer ownership.

Arriving is a job you do carefully because everything is new. Leaving is a job you do at seven in the morning with coffee in one hand, and that is why it needs a written list.

Inside the trailer

  1. 01Fridge door latched and vents set

    The travel latch is there for a reason. A fridge door that opens on the road empties itself onto the floor.
  2. 02Everything off the counters and tables

    Anything not in a cupboard or a sink will be on the floor. Including the thing you are sure will be fine.
  3. 03Cupboard and drawer latches engaged

    Check them, do not assume. One unlatched overhead cabinet redistributes its contents through the trailer.
  4. 04Roof vents and windows closed

    An open roof vent at 60 mph breaks its hinge or tears off entirely. Windows closed keeps road dust out.
  5. 05Water pump and water heater off

    The pump cycling against a closed system on the road is pointless wear, and a water heater element running dry is a replacement element.
  6. 06TV antenna down, satellite stowed

    Crank the antenna fully down. This is one of the five classics and a raised antenna meets the first low branch on the way out.

Outside, and this is where the expensive ones live

  1. 01Awning fully retracted and locked

    Fully in, latched, and check the arms are seated. An awning that unrolls on the highway destroys itself and whatever it hits.
  2. 02Sewer hose disconnected, drained and stowed

    Both tank valves closed, hose drained toward the sewer, capped both ends, outlet cap back on. The disconnect sequence.
  3. 03Water hose disconnected and the inlet capped

    Spigot off first, then disconnect, then drain the hose. The regulator and filter come off with it.
  4. 04Power cord disconnected and stowed

    Pedestal breaker off first, then unplug, then the protector, then coil the cord into its compartment. Not left dangling.
  5. 05Steps retracted and locked

    Manual or electric, fully in and locked. Another of the five classics, and a step that catches a curb takes the mounting with it.
  6. 06Stabilizer jacks fully up

    All of them, fully retracted, and pads collected. A jack left down is bent on the first driveway lip.
  7. 07Walk the whole site

    A full lap. You are looking for the chock you forgot, the leveling block still under a wheel, the jack pad, the hose cap, the dog's bowl. This lap finds something roughly one time in three.

Hitching up and the final checks

  1. 01Coupler latched, pinned and weight distribution bars seated

    Latch closed, safety pin or clip in, bars seated and at the bracket setting you recorded. Your recorded settings.
  2. 02Safety chains crossed, breakaway cable attached

    Chains crossed under the coupler so they catch it if the coupler releases, with enough slack to turn and not enough to drag. Breakaway cable to the truck, not to the ball mount.
  3. 037-way plugged in and lights tested

    Someone at the back while you work through running lights, brake lights, left indicator, right indicator. Every time, because a bulb fails whenever it likes.
  4. 04Chocks removed — all of them

    Count them. Four out, four in the compartment. Driving over your own chock is an undignified way to start a trip.
  5. 05Tire pressures checked cold, and the TPMS paired

    Before you move, while they are cold. Trailer tires run near the sidewall maximum, often 50-80 psi. The psi guide.
  6. 06Tongue jack fully up and the pad collected

    Fully retracted. A tongue jack left part-way down is the first thing to hit a dip at the campground exit.

The common mistake

Doing the walk-around before you finish disconnecting. Do it last, after everything is stowed and the trailer is hitched, because that is when the forgotten item is visible rather than hidden behind the thing you were still doing.

The first fifty miles

Stop at fifty miles and check three things: the hitch and bars are still seated, the wheel lug nuts are still at torque, and nothing has shifted inside. New trailer wheels loosen, which is why the torque check matters, and a loaded trailer settles on its first run.

Also put a hand on each wheel hub. A hub that is noticeably hotter than the others is a dragging brake or a failing bearing, and finding that at a rest area is far better than finding it later.

What to remember

  • Five classics: power cord, water hose, sewer hose, antenna up, steps out.
  • Walk the whole site last, after everything is stowed and the trailer is hitched.
  • Cross the safety chains under the coupler, and put the breakaway cable on the truck.
  • Count the chocks out as well as in.
  • Stop at fifty miles: hitch, lug torque, and a hand on each hub.

What it does well

  • Bracket height is adjustable in the field with a wrench, not a shop visit

What it is bad at

  • Needs a shank and ball bought separately, which catches people out on price
  • Heavier to lift onto the coupler than a friction-bar setup

Common questions

The power cord, water hose, sewer hose, antenna left up and steps left out are the five. Jacks left down and the awning out follow close behind.
