This week we are picking up our new X20E. The TV shelf is on top of the fridge. The back wall has no support behind it for a TV wall bracket, I checked. The arm we have now has a removable clamp on it which we used with the folding TV shelf in our current HTT. The arm has an option to remove the clamp and screw the bottom into something. The arm itself is a Monoprice arm that's pretty heavy duty but we only use it for a Visio 16" TV. I just don't want to put screws in the shelf if its not going to hold it. I would prefer not to buy a new monitor mount/arm.
So what I'm looking for is information on how much clearance there between the shelf and the top of the fridge, or how others are mounting their TV/monitor arms in Jayco trailers with the TV shelf above the fridge. Here's what it looks like, maybe that will help.
