When we purchased our 2004 Winnebago Brave, 34D it had the old Heavy tube type TV's front and rear. Not a Fan.
So I sat about looking at how the front unit was mounted and it was very much well designed and built like a tank. Ok so removed the screws for the surround and then a bunch of screws around the plastic beauty piece, and removed it. Oh heck here's a bunch of pictures to show what it looks like.
One of these days I will learn how to take pictures with this stupid cell phone that arn't upside down, sorry.
There are a bunch of screws holding the metal rack to the superstructure of the Motorhome. Remove all of those. You will be left with two welds at the top into the support bars running across the top of the unit. I used an angle grinder to cut through these welds. WEAR safety glasses and put up some type of non flammable backstop for the sparks to hit. I used a scrap piece of metal to keep anything from getting alight. Worked great.
I should also add, be prepared for some heavy lifting when you remove that tube type TV it is HEAVY and that rack its setting is no lightweight either. I pulled the TV by myself 77 year old Marines can do anything
Have someplace designated to set it before you start stumbling around with it
Now after everything is said and done you will have a nice flat area with a big hole where the old TV was.
I am using a piece of an old shower surround that I had and cut it to fit the opening left behind the TV. And I am using a piece of 1/4 plywood as an underlayment for the shower surround plastic. It is just used to match the white vinyl on the underside of the cabinets.
I used 3/4 inch plywood anchored with L brackets to the metal frame running across the top of the opening. You can swing off that plywood, so no problem holding a 32 inch Vizo flatscreen.
I think I'll use my digital camera to take pictures from now on.
BTW, I am mounting a Dishplaymaker upon the roof and pulled the cable that was prewired for that purpose, cause who wants to drill a hole large enough to fish it out. Not me. I am going to drill a hole in the front cap top just large enough to push the cable up through it, put a cable entry cap on that hole with a lot of caulk and then run it back to the playmaker, stand by for pictures of that. Hope it isn't to bad trying to figure out my pictures at least they are consistently upside down
