My 1975 31' Sovereign
has had a unknown dark history. Most of the outer shell has a second layer of aluminum on the outside which covers the rivets into the channel. I am unable to drill out the rivets from the outside to remove the channel.
Only solution I can think of is to remove pieces of my interior bracing and flex the shell to fit the subfloor into the channel. I do not want to cut the subfloor in half but I am also worried that removing bracing and bending the shell out might distort the shell. I am replacing most of my outriggers so I will lose any reference point for bolt holes.
Any insight would be greatly appreciated!!
