Mounting TV on roof of RV with Aluminum studs

If you remove a ceiling vent fan bezel you will probably be able to see the rafters. I've seen aluminum/foam panel walls with wood rafters. My 2000 FW has alum studs and alum rafters.

Use a stud finder to find the rafters and then drill a small hole into one in the area where you plan to mount and see what comes out...doubt it will be alum. Wood screws will work in alum.

1st off......
Screws do NOT hold in aluminum studs/rafters
That is why they are bolted or welded

Brochure states
6-way fully welded "aluminum cage" construction

5" welded aluminum truss roof rafters w/ 3/8" decking
Welded aluminum framed fully laminated 2" sidewall

Securing a TV mount to ceiling or even wall with be difficult due to the screws NOT holding in aluminum

Now if you were to mount it to wood cabinet :H

Sorry don't have good solution other then removing a ceiling panel and building a wood support to screw into.

The ladder on my 5er is attached with screws into the aluminum frame. And is solid. I have climbed it many times. At least it was solid until I caught the corner of the rear cap on a steel column coming out of storage and pulled the rear cap back about 18" including pulling the ladder screws out of the aluminum frame. :S

All sorts of stuff screwed into my aluminum frame like the water heater, door etc. I like showing off the weld quality around my water heater so here.......:)

Bet the end cap is NOT aluminum studs or wood blocks are installed for ladder mounts

As for frames etc......not much load bearing so screws will hold but can strip out very easily.

Weight capacity/Load bearing requires nuts/bolts or welding when aluminum is used

Sorry, I rarely disagree with you. But, on this you are wrong. Use NON self-tapping screws when securing to aluminum. That way you will have screws that will tighten and stay tight. Doug

My rear cap with ladder still attached was pulled back enough to see everything behind it. The ladder screws went into the aluminum framework and no wood support behind.

Thanks for all of the feedback! I took off the ceiling vent bezel as rjxj suggested, then used my endoscope to look up in the ceiling. The studs are definitely some kind of metal, presumably aluminum. I tapped on it with a crowbar to be sure.

The stud was large and sturdy enough to hold a TV, but I want to be sure the screws will hold. I can see there is some debate on that topic.

I did some preliminary research and I see people doing it in houses, so I don't see why it couldn't be done in an RV. This video was interesting. I also read a lot of people use toggle bolts. https://www.youtube.com/watch?v=1kgC7vfhnOE

Regarding mounting it to a cabinet, I would like to do that but the positioning is awkward. My wife and I explored that option and it would work but we wouldn't be able to move the TV at all. It would be stuck at one angle. So it's either get a smaller TV (we like our 32 inch for the bedroom) or find a way to mount it to the ceiling.

I think if you get a mount that is easily removable or can take the tv off of it while traveling, it would reduce the stress on the screws and make for a lasting mod.
