So long story short I have a
1968 30ft that I brought home to replace axles and fix rearend separation. Yea that was a month ago and I've almost done a full shell off restoration. I'll post tons of pics and lessons learned when I get done. The tip I thought of and wasn't sure if anyone else has done it this way. I get a large hole saw and drill around all the floor screws. Then after all bolts in the c channel are removed I've been able to pull the floor out in one complete piece.
Just thought I'd give back some since the wealth of information on here has been a life saver. Now back to work before the city and HOA starts finning me lol.
