What are yous guys skinning the roof with. I'm 5' wide (I mean my TD is 5') and plan to use 5X5's that are 1/8 to bend easily. If I then skin that with AL is the 1/8 enough or do I need to put on two sheets for the added strength? Or should I just use something else that is 1/4? I'm thinking that 1/8 would be sufficient with the foam insulation underneath and AL on top, am I OK with that? What are your thoughts? I still have wireing and insulation to install but I'm thinking ahead.

The 1/8th is plenty. (Besides, do you think you can bend 1/4"? Don't know your profile.)
Also, aren't you just going to use luan if you're skinning with aluminum? If so, your choices are pretty limited and already made for you, especially at 5 wide.

That's what I was thinking but wanted to make sure. Things are moving along pretty well after my setback. I'll get more pictures posted soon.
Thanks

I put 2 layers of 1/8" ply on my roof, then I skinned with aluminum. I think that if one layer would have been fine. If you aren't putting aluminum on top, do 2 layers.

Rocky, is there any difference as far as possible damage to your aluminum goes depending on your substrate?
The Cubby plans only call for 1/8" under .032 aluminum. (Is that number right, or did I screw up the decimal point?)
But again, these are the CUBBY plans on top of the 1100# HF trailer, where everything is recommended light.
And Jim--your TD is looking AWESOME!!!

My sides only have one layer and they are fine. The 1/8" holds up just fine, no dents or anything (except one). It only has a small ding caused by the door flying open and slammming against the side. When I did the top, I staggered the 2 layers to prevent leaks in the seams, it may have slowed the leaks but it didn't stop them. I used .032 (you had it correct) aluminum on the top and sides.

If you use two layers of 1/8...what do you glue them together with?

You have leaks in your roof? Any idea where it's coming from?

When I took the trailer out for the first time, it was as Lenny puts it, a monsoon. I think everybody's trailer leaked that weekend. I didn't have the aluminum on it so it could have come from anywhere. It doesn't leak anymore, except where I cut a hole in the roof and haven't yet covered it.
I used polyurethane caulk, spread with notched scraper, to glue the second layer to the first.

Ah, ok. Now it makes sense. I didn't realize that was before you had skinned it.
Eventually I'd like to skin mine with Filon, but after seeing the prices I think that may be a long way off.

I used epoxy. Brushed it on, and clamped....

Steve used two layers of 1/8" plywood on the Lil Diner. I'm betting he used epoxy, but I'm not sure.
I would have used titebond III.

That makes me feel better. I couldn't imagine how water would get through the AL. Good to hear 1/8 is all I need. 1/8 it will be.
