What do you put under your stabilizers and trailer tongue?

Add a swivel wheel to the tongue.

Any trailer I've owned has wiggled enough as it is so I use a set of BAL X-Chock to help minimize the effect ... adding a wheel to the tongue jack would only exacerbate the problem and defeat the purpose of the X-Chocks. When hitching up there's no way I'd be able to shift the trailer to match it up to the hitch ball even if the TJ was equipped with a wheel ... instead, the trailer stays put and I use a Swift Hitch Wireless Camera System to hitch up and can line the hitch ball up perfectly to the trailer coupler with just one try, every time. :B
