I will look into that thread right now.
Two things that were pointed out that are particularly interesting to me. 1)the fact that one jack may be off the ground altogether when lowering. I have experienced this and thought "well that can't be good, but how would I avoid it?" It's good to know that this may be unavoidable.
And 2) the other person not familiar with lowering the camper cracking the valve all the way open and it going down to fast, and too far. I'm a very patient person and I wouldn't yell about something like that. It doesn't seem worth it and it's not like things can't be fixed. It would've sucked if something worse had happened, but we got through it.
