The Perfect Class C at 32.6 feet... WoW!

[emoji3] It’s similar to a doughnut hole.

This is the core of the hole I drilled out of the side of our Flagstaff when I installed an exterior plug for a separate 120v circuit.

Interior on the left, exterior on the right.

Hmmm ... what is it that's special about Azdel walls?

The walls of my Winnebago certainly "look" like they're built that same sandwich way (thermally bonded white cellular foam stuff in between two other inside/outside flat materials). I'm not sure about the outside wall material being used in Azdel walls. Winnebago uses fiberglass in the outside material of the sandwich.

I guess I kindof assumed that all/most RV coach walls were made the same way. What other ways are they made?

If your unit is a micro light I think FR used Azdel wall in them

Perfect spot to mount a projector TV aimed at the window shade on the opposite wall?

I've always been curious about this. Anyone tried it? I'm too lazy to run an HDMI cable to the other wall, otherwise I think I'd try this.

From their website.

“Azdel is a composite panel used by top travel trailer manufacturers as an alternative to Luan or other plywoods. Azdel composite panels are resistant to rot, lighter than wood, and provide better insulation among other things.”

So no plywood panel beneath the exterior fiberglass. This is supposed to protect from water infiltration causing delamination of the external skin.

I look at the way jayco/Entegra builds their sidewalls (no Azdel) and I wonder about 10 years down the road. I know what Azdel will look like. Can we expect the same from the others?

I know we’ve wondered off course from my original post. But it is a curiosity is it not?

Yes it is and it is something that is at the top of our list as we research our next RV.

It protects only from delamination. Water may still get into the walls and cause all sorts of other havoc. It just wouldn't be quite as obvious by looking at the outside skin.

Well no matter it’s a great product the best on the market, no where does it say that you can stop sealing penetrations such as windows, not very likely to happen. I’ll take that construction any day. It’s not hiding anything. As I stated earlier there is a raw wall board that they made into there sign with printing on it saying Coachmen in weather 24/7 , it shows nothing inside or outside, no tricks.

I don't believe there's any conversation to be had about the quality and longevity of Azdel. It's like a werwolf... Everybody knows there's a werwolf and you can't see it in a mirror! Unlike Dracula who can be killed with a silver bullet!

Azdel is good stuff. No argument there, and I've never said otherwise.

It won't protect you from OTHER damage caused by leaks though. It only keeps the skin from being damaged.

I think I just said that, nobody ever claimed that other water can’t intrude with it.

Point being: If you have a leak, you have a problem whether you have Azdel or not. If you don't have a leak, then you're not likely to have delamination, whether or not you have Azdel. The best course of action is to take steps to not have a leak and not worry as much about the wall material. Getting Azdel is great, all else being equal, but IMO not a deciding factor.
