Hi Folks,

I was thinking about mounting a small wall mounted bottle opener outside the door of my 150, but I am not familiar with what kind of bracing/structure is is back there. Metal? Wood? 1x3's? It obviously doesn't take a ton of strength to open a bottle, but there is enough pressure that if its not into something solid I think it could peel the siding off. 

Pic is the style of what Im thinking. Thanks for the help!

I don't think there's anything behind the skin except insulation, unless you're lucky enough to hit part of the aluminum framing. The 150 is built similar to the 177 shown here.

f you have an awning, maybe to the support strut with screws short enough to not interfere? Or maybe down low, next to where the awning strut is screwed in, looks like there are plywood backers there.

Very interesting picture, thanks! 

That it was I assumed, but thanks for confirming.

So that last picture with the insulation; the aluminum siding is placed right over the insulation?

Unless you have the radiant barrier, I believe the outer skin goes on next. And, the barrier isn't much more than a sheet of aluminized plastic. What else would there be?

If you don't hit one of the metal studs you are in trouble.

Do you think that frame would support a 100 lb air conditioner?

Yup if the welds are good that will hold a lot more weight than that. Our friends bought a reto Airflyte. 2x2 wood construction. The aluminum frame and insulation factor is the reason we bought our 176s in Arizona.

Or...you could buy a wooden thing like this off etsy and not make a hole in your trailer...you could just set it on the ground, a table, etc. and use it inside or outside.

maybe you can just buy a bottle opener and put a string on it and hang it off the handle by the door if all else fails...lol

I believe the 150 has a wood frame, but either way, you may be able to use an electronic stud finder. They search for changes in density behind the surface.
Just a thought.

Maybe you could put one on the hitch?

We did screw a track for the awning we got near the top...

how would I find the studs behind the exterior sheeting? I plan on installing a dinette table universal wall mount to the outside so I can use the interior dinette tale outside.
any suggestions please advise.
