Here's what we use: BAL - Innovative Products for the RV Industry
It's lightweight, easy to set up and works real well for us. I typically leave the nose of our rig a pinch high until I have the tripod in place & then bump down the landing gear 2-3 times to firm it up. We then go set the rear stabilizers after that.
We might have installed another system, but would have had to relocate the spare tire as it is between the front legs of the landing gear. We tried this tripod instead & so far we're satisfied...even though we still do get some shake...we can live with it.
