Jim has covered the major points in the removal of the interior furnishings. The one thing I found with the work I've done on mine is that there are dozens of screws in places you would never think. Some from the factory and some from a PO.
The worst were the screws going through a bracket between the counter top and the fridge vent.
Pull the cabinets out slowly, bet you find a hidden screw you can't get to binding things up.
Just an aside, I was surprised to find that the wood in the GT was ash. Looks kind of like oak but a much lighter color. Went through a lot of pricey lumber rebuilding benches and tables after the PO had converted the coach into a rolling office of sorts.
Good luck, Tom.
