In that case, Forest River should be paying you to do a commercial on the toughness of their fifth wheels.
You must have a ton of miles on that puppy!
About that jammed jack, I know we all have to be careful when retracting them, as they don't like being retracted all the way, as the gears could possibly break when the jack bottoms out. There really should be an electric cutoff switch to cut the power before they bottom out, because there are no warnings about the potential for damage. No big surprise there, as we are pretty much on our own as far as learning about our campers goes.
