Before our 2002 Lance 1130 we had a 1997 Lance 165, both campers were (in my opinion) too unstable to use off the truck without some support under the camper. I was not afraid of the camper toppling over front to back but side to side movement on the front jacks put stress on the jacks. EVERY time I took it off the truck I put some support under at least the front of the camper. I know just getting in and out you could see movement and stress being put on the front jacks. For me it wasn't worth it not to put some kind of support under the front to relieve the pressure on the front jacks
