HELP , want to mount TV in Trillium above sink

[Darren Pettis]

Douglas , I would prefer to just drill the shallow holes and mount the bracket there above the sink but what are these Butterfly nuts and bolts ?
Are these some kind of special hardware that can be supported from between the wall layers ?
I just don't understand how I can get bolts to face inward to the trailer without having the nuts on the outside of the trailer to support them.
I wish I could get between the walls

Google pop-rivets video or go here for a short lesson. You can buy a simple tool for less than $20 and it will last forever.
BTW: If you have a FGRV you need a pop-rivit tool in your tool kit.

There are few tools easier to learn how to use than a blind riveter!

Here's an good brief intro video- and if you watch it at Youtube they'll suggest a whole bunch more:

Thank you all for replying, this is great info.
So are there such things as threaded rivets (so I can mount the TV bracket)?

Yep, they are generically called "Riv-Nuts" Some can be installed with a standard pop-rivet tool, others require a special tool. Try to find a real metal and hardware supply store near you or shop on line.

I use these a lot but not in Fiberglass and not for a load cantilevered off a wall at a right angle.

I urge you to consider hanging from the shelf above,the load will be better carried that way in my opinion and you can also work easily from inside the cabinet to reinforce the fiberglass too.

Harbor Freight has a tool with assorted inserts for <$20 that works well for the money. I've used mine to mount roof racks on cars.
