Bathroom Floor replacement

I have a 71 Excella 500 that i just bought. It has the rear bath. The floor at the very back of the bathroom is a bit week. How hard is it to fix that? Keep in mind i plan to pull most of the bath apart anyway to freshen it up. Not to particularly fond of the dirty off white look it has.

Floor repair depends on how bad the damage is. Lots of threads on this subject on Airforums.

Don't tear out the bathroom yet. Clean it up and live with it for a while. How about some photos?

There's lots of information here on the forum about Airstreams with the rear bath and the sagging in the frames and such. If the floor has signs of damage don't neglect looking to the cause and stabilizing it as you delve into repairs.

Do a search for (dreaded) "rear end separation." Rotting rear-end floors and rear end separation go hand-in-hand, especially on 70's era trailers.

So best case scenario, all you have wrong is some rotted plywood, and you can scab in a patch.

Worst case scenario, your rear-most sheet of plywood will be so rotted that you will conclude that you might as well replace the whole sheet. This can be done without lifting the shell, but it will be a PITA. When you remove this sheet, you will find that your rear hold-down plate has rusted into near non-existence, your rear most frame cross-member will be all but missing, and the last 2-3 ft of frame will be cancerous with rust. The relative motion of the shell and frame will have caused the rivets in the bottom of the rear panel to begin tearing out as well.

My '73 had some floor rot in the rear that I didn't even notice when I bought it, and I ended up doing a shell-off.

good luck!

I replaced the bath and rear floor in my 73 overlander. If you click on the blog link below you can see what I went through. Good Luck.
