Here's my restoration. How's yours going?



If you look closely in the lower rear quadrant of the photo you can see ductwork. I'm assuming this is not typical. All the yellow stuff is spray foam insulation. Comments?

Not sure if this the "before" or "after" resto, but looking good! I think you can re-use much of that insulation, possibly in a dog house, or just to hold the ductwork up off the ground.

Lifted shell off about 2weeks ago. Stripped plywood deck. Cutting stabilizers off to remove belly skin. Found wire harness encased in insulation. Will need to replace that since PO cut hookup off. Tank will probably need replacing also. Duct work going away. Don't like the idea of floor penetrations.

It looks as if the duct is original. there's a 7' section that could only have been installed at the factory, I'm assuming. Does anyone have any insight on this? I'm thinking it needs to go so I can properly clean, prime and paint the frame.
Thanks,
Shawn

No duct work beneath the floor on my '72 but ALL the above floor ones were mouse spice-road super-highways complete with dung dunes. That said, I would have no hesitation removing duct as long as there are no plans to restore it back to original.

I think that may be poured (sub-floor) foam insulation - sure looks remarkably free of rust, has that trailer stayed in the SW area its whole life?

That sure looks like a lot of frame for a mere 26' trailer! Looking good so far, keep the momentum up and don't let the devil in the details distract you... or something to that effect, anyway.

No under-floor ductwork in my '72 either; would that have been to keep the water and waste tanks from freezing?? In any event, doesn't sound like you need it. Have fun with your Large Resto!

Unless you are in extended cold weather I guess it wouldn't be a problem, but since she is naked, why not add so to protect you from such a "chilly" occurance?

I had the exact same set up. I strangely had no evidence of mice in my trailer whatsoever (lots of wasps nests) I removed mine so I could work on my frame. I wish I would have put in new duct in its place. I have to run duct work behind cabinets now. If I could travel back in time and have a chat with my past self I would tell him to plan your interior prior to floor replacement. You have a big frame with a lot of space for ducts, grey tanks, fresh water tanks etc. It can free up a lot of living and storage space, just sayin...

I had a '68 22' with ducts below the floor and spray foam insulation, all from the factory. The duct system was great, well insulated and took up no room in the unit at all. The heat was forced out of the furnace, down into the ductwork and through the length of the trailer (but it was short). With the body stile change in 1969 they went with the above floor ducts which cluttered up the cabinets. I always liked the '68 system.

I tore into my 68 26' Overlander last year and also found the ductwork within the frame and factory sprayed insulation (and the spray insulation was not applied very well or throughly). My ductwork was not insulated and I cut it out. It also had a small hose to blow heat onto the black tank.

I've installed grey and and fresh water tanks within the frame. Heater ducts will be within the cabinets.
