Answered What is the thickness of a Newmar wall, inside to outside?

[RandyB]

In a separate thread I was asking about adhesive recommendations for sticking an aluminum track back onto an exit window. So far, there is nothing I’m all warm and fuzzy with.
Replacement glass is made from solid gold, apparently. $904 from Newmar. It appears that replacing the entire window assembly is the only means for peace of mind. $210 and it has a screen!
I have the rough opening dimensions for a typical exit window from RecPro. The height is OK, but the hole will need widening by 1 5/8”. That’s no big deal. Easy enough.
For a complete picture of what I’m needing to order, I need to know the wall thickness. Is it safe to assume that all late model Newmars have the same wall thickness?

Does anyone know for sure the wall thickness dimension? Outside skin to inside panel.

2017 Ventana LE 4037, bedroom window, drivers side, in the full wall slide.

The moment I posted above, I realized I could rig up a caliper and a block to measure the thickness without disassembling anything. It turns out that 2 9/16” is the answer. Here’s my rigged up measuring device:

I don’t think you can replace the existing window with a wider one since there likely is framing on either side of the window.

The morning dew and condensation will show it.

It's pretty easy to remove the inside retaining ring of the window to see what's in the wall and see if there's enough room to enlarge. I've done it a few times, and the window never moved out of position. I'd recommend taping the window on the outside though, just in case. This is assuming you have the frameless windows in your coach.

I sure hoped you were wrong, but you were spot-on. When I removed the trim ring, it’s very evident. Then I recalled the factory tour and how Newmar uses a router to cutout the skin after it has been installed over the framing.

So, I’m in a real dilemma, now. Hehr out of business, Duncan/Lippert has taken over. Now negotiating, but they only want to sell complete assemblies. It’s obvious now that I MUST stay within the existing rough opening, but no one else makes such a critter especially for a 2 1/2” thick wall. Sigh…

Stay tuned and I’ll keep updating as I proceed.

Have you tried taking the glass and the aluminum track to a local glass shop. They may feel
Comfortable with a method and adhesive to re-attach it

You beat me to it.

Yup, that's what I'm going to do. Go back to the beginning and start over. I've made a 1/4" Lexan window to seal-up the coach as I have the glass out for evaluation and repair.

What was the end result? I’m having a heckuva time with a 42x20 tear drop window replacement on my Thor Palazzo pusher. I took the window out and to a glass shop, but didn’t get the warm and fuzzies with what he wanted to do. Why are RV windows such a dang pain???

Quick quote came up with $427 for a replacement window. It’s still frustrating because there are 42x22 on Amazon through RecWorld for half the price. They’re just a hair too tall for my rough opening.

 

[RandyB]

What was the end result? ...

Oh, yeah, I never did finalize. I took the glass to a local glass shop that does residential, commercial and auto glass. They re-attached the rail and all is good. I don't know what product they used.

Due to storm damage and window fogging I had to have two of my coach windows replaced. These windows are Hehr brand as well. While they have been sold they are still making replacement windows. I have replaced windows in my coach myself however this was covered by insurance so I had a glass company handle it. It does take a while to get the glass but they were perfect when I got them.
