Loaded Semi gets stuck coming out of the federal reserve

So rather than call a wrecker, wouldn't it be prudent to slip under the tractor, disconnect the leveling valve linkage, and over-inflate the driver air bags? Maybe you could do that on the trailer as well? I don't drive anything that new, but I'm pretty sure things haven't changed that much.

 

My leveling valve would be almost impossible to disconnect while hooked to a trailer. It's up underneath the 5th wheel so getting your arms in a position to get the cotter pin out would be challenging, getting it disconnected - forget it.

I would have tried cranking the landing gear until all the weight was off the tractor, disconnect and pull forward a foot, then put some 2 x 4 s behind the drives, back up and recoupled.
