RV Stabilizer Jacks

Stabilizer jacks steady a parked RV — they don't lift or level it. Their job is to take the wobble out of a leveled rig so the whole trailer doesn't rock every time someone walks to the fridge. This category covers scissor jacks, telescoping and adjustable posts, tripod kingpin stabilizers, and the rebuild kits to bring older hydraulic camper jacks back to life.

Picking stabilizer jacks that actually kill the bounce

One rule governs everything below: ask a stabilizer to carry real weight and you'll bend it. These are support devices, not lifts, so the ratings you'll see describe how much load they can steady — not how much they can raise. Get that straight and the rest is picking the right style for your rig.

  • Type. Scissor jacks like the Ultra-Fab 6,500 lb units bolt to the frame and crank up in an X; telescoping and adjustable posts like Camco's The Boss or the Valterra universal drop straight down; a tripod steadies a fifth wheel's kingpin up front.
  • Capacity and height. The rating is a support figure, not a lift figure. Buy for the gap between your frame and the ground at your usual sites — a 24" or 30" scissor covers most rigs, tent trailers use shorter 20" sets.
  • Crank method. Most scissor jacks take a 3/4" socket, so a cordless drill spins them up in seconds. Snug them firm, not gorilla-tight — over-torquing lifts a wheel off the ground and defeats the point.
  • Rebuild vs replace. Hydraulic camper jacks can be brought back with a kit like the Rieco-Titan RMK2 rather than replaced outright, which is worth checking before you scrap a leaking pair.

Level the rig first, then stabilize — get the trailer sitting right with leveling blocks and chocks before the jacks come down. On soft ground, set a jack pad under each foot so it doesn't sink, and if you need to raise the nose to couple, that's a tongue or landing jack, not a stabilizer.
