I had them on my 04 Jayco for 2 years (different brand but same thing) and moved them to my 09 Passport, I won't have another TT without them. They lock the TT in place, with kids and a dog they are awsome, I did add 2 scissor jacks just in front of my tires and I have zero movement.
Only downside is the black tank does not get sloshed aroud to help prevent mounding, so on long trips when I have to use my waste tote I will unlock the stabilizers for a couple hrs and let things get shook up before dumping. My toilet dumps into the shallow end of holding tank so untill its half full no liquids under toilet.
Ultra fab brand. I also have 30" jacks.
