[VAC] Rotten floor supports!

[Jeffrey Engle <bedheads@xxxxxxxxxxxxx>]

Wouldn't you know it, just about the time you think you've been 
everywhere there is!
The other day I cut out a small piece of floor in the rear "Trunk" (1977 
sovereign center bath, rear twin 31ft.) to replace it before it got too 
bad and found that the supports (or otherwise called "Longitudinal 
tubing") was rusted clean through! NASTY! .Well since we've had this 
there's a double bed over it and I'm afraid i'm going to have to remove 
it, the floor, the belly pan...Any help here?  thanks  jeff OH and by 
the way, yes this is the same Jeff who recently enquired how to get his 
pics online...of witch I'm working on this very minute! Jeff
