I think a combination of the steadyfast or JT's along with the X-chocks has proven the best results. Or, like a lot have done, fab your own version of the steadyfast or JT. Some say the tripod works for them. We've tried that, and it worked some, but think the diagonal bracing in the landing gear and rear stabilizers would work better. Fabbing diagonal bracing on the jacks is still on our build it list, so I can't tell you first hand on that one yet. Just know that's what I read the most of.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
