Hopefully when I get my rig back after waiting for service for 5 mos., I'll be able to use it more, that said, how long can you leave the 31UL on jacks with slides out?? Should I pull-in the slides and lift the jacks if I'm leaving in for awhile (few days)??? I like to leave it open (jacks down, slides out) on my concrete pad because I'm always putt sing with something, next on the list is to install something in the power cable box so I can pull out the cable and feed a foot back into the box through access hole to hook-up rather than pull all the cable through the hole.. kinda thinking of Marinco twist-lock male/female...
