When we first got ur 72 it had a mold problem also. I used Mean Green which can be picked up at Walmart to scub it down. We then placed an ozone machine in it for 24 hrs to kill the mold and havent had any problems since. Good luck! I love the 70's models also.

Quick and dirty:
1. Yes
2. No, if you plan to tow it.
3. Your choice, but for restore/resale value, both 2 and 3 should be YES.

Welcome to the forums, good luck with the project.

Removing the inner skin is a no-no? I guess I could see how, just never really thought about that.

thanks for the info. is there a good way to remove the insulation? without removing the aluminum panels? what do you think about spray foam insulation? should i be in another forum

Michael, click on the Forums tab up top then scroll down the page. There are many sub-forums covering the topics you are asking about. Try searching thru those, lots of good info there.

I don't know of a way to remove the old insulation without taking the interior skins out. As far as the spray insulation goes, that idea has been tossed around, but I don't know if anybody has successfully done it.

Michael-

Greetings- The interior skin is structural as well as adding interior surface. The ribs are kept lateral by the exterior and interior skins. We have tossed around the idea of foam insulation but there are too many what ifs. What if it over expands, what if you need to get back into the inner layer for plumbing or wiring, etc. Plus you would still need to remove the old insulation prior to foaming. Removing the inner wall skins is lot easier than you might think and reinstalling is just as easy. All it takes is time and carefulness. Check out the other threads. Good luck and keep us posted.

The interior skins help keep everything in place, so they should be retained. To remove insulation, you will need to remove the interior skin, replace the insulation, and replace the interior skin. You can clean the mold (mildew) off the skin while you have it out replacing the insulation.
Expanding foam insulation is not recommended, it will crumble to dust and wind up being useless.

I too, looked into the spray foam. the company I was dealing with, had done the cube bodies of the trucks for thier company. These were aluminum sheet over a ribbed frame. In one vehicle, they injected the foam between the inside and outside panels. It had very noticeable outward bowing from rib to rib. on this one, they had a plywood tnterior. Thier thoughts were the that the expansion caused the bowing. On another vehicle , they removed the inside plywoodas to allow the foam expansion to be able to go away from the exterior. This only helped minimumly in the bowing effect . End analysis thoughts were that the heat from the foam cureing caused the skin to expand and streach.
Needless to say, I didn't go with the foam. We chose HVAC duct insulation.
