I use bal x-chocks between the tires, and bought a set of 4 aluminum jack stands from camping world that I use just before and after the pair of axles (on both sides of trailer). Looking from the front of trailer, we have the front stabilizers, then a jack stand, then the first axle, the second axle, a jack stand, and then the rear stabilizers. this stabilizes the trailer very well, as it takes most all of the bounce out of the tires/axle suspension. We have a V-lite 30WRKSS. Hope this helps.
