Conflicting info on levelling with stabilizing jacks or not.

My trailer has 4 levelling jacks; each corner. Plus the tongue jack.

I have read that people use a block of wood under the tires to level side to side. I could do that when I am very off but I don't see myself carrying and adjusting shims of wood until it is level.

So... Can I use the scissor jacks to raise it a little but to make the level perfect? Yesterday I used the back right corner with my ratchet to raise it maybe 1/2-1" and the 3 other corners just with the drill until contact with the block of wood.
  • Look up the specs on your scissor jacks. Some are rated at a certified 6500 lb load capacity. Some have feet that stabilize only and carry no load. I use all four of my scissor jacks to level a inch or two without any problems.

    It's not the stabilizers and their capacity that is the problem...it's the frame. Cranking them down good and tight is OK, but Lifting and using them to fully level is not a good idea.
  • I'll get a set of levelling blocks. I wanted to make sure I don't spend and carry things I don't need. Those are cheap and seem much easier than bringing a collection of wood planks and trying to stack them as a ramp to drive onto.

    Thanks

I use all four of my scissor jacks to level a inch or two without any problems. They won't bend or rack your trailer because they're connected to the frame, even better than the load points of the axles. Going down the road at 65 mph puts move stress on the frame that the jacks.

    They are not designed to lift/level and neither is the frame of you trailer.

    For side to side, drive up on (shims) as you call them, or get your self a set of very handy, lightweight, easy to store and easy to use Lynx Levelers.

    "A small amount" means no inches. Not 1 inch, not 1/2 inch, no inches, zero, nada. The idea is simply to make the jack base tight against the ground. If you actually lift the trailer, you will require the frame to flex a bit, which it was not designed to do, and you can bend it, which will cause a host of other problems from leaking roof seams to cracked plumbing drain pipes.

    Driving up on shims, either wooden blocks or those orange plastic ones, your choice, is the way it is done. Once level, you lower the jacks and crank them down just enough so that they are tight against the ground. Their function is simply to take the bounce otherwise built into the springs out of walking around inside the trailer.

  • From Skyline manual:
    "5. Lower stabilizer jacks, placing wood block under foot as necessary, until they make firm con- tact with ground — Do Not Overtighten or try to lift trailer except for small amount needed to level."

    What is a small amount needed? Is 1" a small amount? Earlier step is

    "2. Before uncoupling, level the trailer from side to side with suitable lengths of 2” x 6” wood blocks under the trailer wheels. Place the wood blocks on the ground forward of the wheels, and tow the trailer onto the blocks. Block the wheels to be sure the trailer cannot roll."

    So anything smaller than what I can do with a 2" piece of wood is OK to do with the jacks? Or should I bring 1" and 1/2" pieces too? I would have liked a hard number of where the limit is.
  • You are talking about stabilizer jacks at each corner of your trailer not leveling jacks. Stabilizers are not made to handle the weight of your trailer. Read your owners manual. Use the wooden blocks under the tires for leveling.
  • Where does the "conflicting information" come from? Everything I have ever read or heard say not to use the stabilizing jacks to level a camper, thus the name stabilizing jacks not leveling jacks. Just curious as to where you read or heard otherwise.
