I started out using the jacks as recommended by the dealer when we bought the 3500RL in Nov. 2005. Only used them a couple of times and didn't see they really helped much. Also its a pain to climb under all 3 slides to put the jacks in place and to take them down when moving to a new spot. So, haven't used them in the last 8 months and everything is still working fine. Anyone interested in a set of slide jacks?
I agree with all the ideas posted on MOC. Good Luck, Bob
