Spoke to the OP. He has taken the RV to a Trailer Fabrication/repair shop. They unfortunately have to stay in a motel until the work is complete.
He is going to be personally involved in removing the propane tanks and tray support, hydraulic pump along with battery pack on drivers side front. He will also be removing the lower front cap. He will have a shop employee working with him to get the RV opened up to do the actual repairs. I am sure I missed a few things that have to be removed to actually have room to do the repairs.
The Shop was highly recommended by several RV facilities.
This is a big job but the OP knows what he is doing and I am sure it will all turn out well. It's simply going to take time to remove everything to get to the main issue and then re install everything.
