One of my biggest concerns was all of that front weight of the unit, plus people and cargo on the tongue jack. Knowing that the 'stabilizers' are not made to hold very much weight at all, I wanted a better 'foundation'. I added a pair of scissor jacks the first year that we had the unit to support the front. Laying under the unit and looking for a good placement area, I knew that that mounting them permanently, I would have issues with the low hanging skirting. I bought a pair of SaveAJack.com
These I bolted (not screwed) onto the frame rail in a location back from the front stabilizers. As said before, the door side of the frame rail has the gas line running next to it and so I offset the plate (Sav-a-jac plate) that is bolted to the top of scissor jack so the scissor jack does not slide under or close to the gas line. I use only the two scissor jacks in the front of the unit for two years before I install the back scissor jacks just this year. With the two scissor jack in the front, it is night and day difference in stability. Add the large X choke and it is better. The back jacks were no priority at all to me, because my main focus was the front, weight and movement issues. When I added the back scissor jacks (as said in my last post) this just finished out the full support of the unit.
The electric 'stabilizer' in my view point are a waste in so many areas and these units should come standard with scissor jacks.
