I need something and don't want to reinvent fire to get it...

I'm not sure if this is a joke but once that wolmanized lumber dries, it cracks and becomes useless.

 

then get more. its not rocket science. put something under the leg pads. or carry around some railroad ties in your bunk. they last longer.

 

A few years ago we had this happen to a loaded trailer. We cleared the other trailers away from it and backed 2 bob tailed tractors up to the sides of the trailer mid way to the back and dumped the air bags. Backed the rear frame rails from each tractor under the trailer with a 4x4 on the frame, then inflated the air bags until it was high enough for a 3rd tractor to get it's frame rails under the front of the trailer. Eventually we got it high enough to get some wood under the gear and hook it up. Pain in the butt, but it worked.

 

Just put some 4x4 under it . find some old dunnage
