On our Keystone Cougar, we gently use the slides on a limited basis if all the way in or all the way out- Being careful not to step on the inside edge, or within...6-10" (whatever a big step is ;) )
All the way in, the slide supported against the outside of the walls of the camper. All the way out, supported against the inside of the walls of the camper and the edge against the floor.
Now that is if we must. In all reality...now that we upgraded to the 4 GC batteries, I just find a spot wide enough and zip it out and back in when finished, say for a lunch stop in a rest area or fill stop.
Battery *should* recharge along the tow. I have the charging relay and such...but I should actually test that sometime.
That is all. Back to your regularly schedule program :)
