rtaylor0830, I no nothing of the 6 Jack system (I'm guessing Lippert), but with our BigFoot system, I do work on unit (20K#) using system to elevate the unit. Maybe it's because I have good insurance :B, or just "feel lucky";). I'd suggest contact the system manufacturer, and ask. But, probably the answer is no! Due to liability issues. memtb
