John Canfield:
Excellent!  Looking forward to part two.

Part two of this project – the mounting of the TV

For mounting, I choose to use the Winnebago designed and manufactured TV mounting bracket. This kept me from having to design something from scratch, and assured me that it would stand up to the rigors of motorhome travel. I have designed mounts in the past – specifically for a 1999 Adventurer, when I replaced the CRT and replaced with an LCD, so although designing a mount is not foreign to me, I was also looking at saving time.

The mount is two basic pieces. The main support that screws into the cabinet and the TV mounting panel the attaches to the TV, then to the main support. The Main support sits on the bottom of the cabinet, and attaches with four ¾ #8 screws. I did need to add a 3/8 thick piece of wood between the bottom shelf (floor) of the cabinet and the bottom of the main support. This was accomplished with a trip to Lowe’s and purchasing a 24x3/8x4 inch piece of wood. Available as “craft wood.” The interior of the front overhead cabinet is “stepped.” The front section lower than the rear section. The support overlaps the exterior “rail” of the cabinet on top and each side takes two ¾ #8 which go into the frame horizontally and one ½ #8 that goes in vertically. The TV mount has a “hook” built into it that goes over the top of the main support frame, and then attaches with one ½ #8 one each side. I found that a #8 is to large, so I intend to thread the holes in the main support so a #8x32 or 24 bolt can be used.

I also purchased and installed the two vertical “electrical” panels to install along the sides of the main TV support. In a factory install these panels are designed to hold an electrical outlet, speaker switch and the like. I installed them just to close off the area behind the TV so I did not have go chasing items that might slide in the cabinet and get lodged behind the TV. The panels attach to the upper “step” of the cabinet on the bottom, to the back of the cabinet and to the ceiling of the cabinet with ½ #8 screws on the back and top and ¾ #8 on the legs. Again a 3/8x6” spacer was required under the bottom “legs” of the panel.

Part three of the series will deal with the TV bracket and the attachment to the TV and the main support.

Part three of this project – the mounting of the TV bracket

The TV mounting bracket – the section that attaches to the TV proved to be the most challenging. The mount bracket is designed for a Sharp LCZ6D43U 26 inch LCD. Physical dimensions of the Sharp TV are 26x18x3. It also has a VESA 100x100 mount. I choose a Samsung LED LCD, model UN26D4003. This TV is slightly smaller, but the main difference is a VESA 200x100 mounting area. This meant that I had to adapt it down to a 100x100. To do this I used two pieces of ½ x1/8 flat aluminum, each about 9 ¼” long. I drilled two holes in the center of each strip, matching the factory mount and put in #10 x 1” bolts. I connected the flat aluminum to the TV using industry standard M4x70mm bolts.

During the lay-out of the mounting bracket to the TV, I noticed that the TV attach point were relatively high on the TV. The mounting holes in the bracket, designed to match the slots on the main support, seemed to indicate that the mount of the Sharp LCD TV was more on center on the TV. If I were to use the “factory” holes on the bracket, then the TV would be low, well below the cabinet bottom. Since there was space on the TV bracket, I drilled another set of holes higher on the bracket. This way the TV would mount to the main support toward the top. Making this modification of course caused two, later to be three other problems. First, on the bottom of the TV bracket was a second square hook, which looked like it was designed to catch and support the bottom edge of the TV. This hook rested against the back of the TV I was trying to install. Choice was to cut this support hook off. As I examined the TV bracket, I noticed that the support hook on the bottom was a separate piece of steel that was riveted and spot welded on the TV bracket. I drilled the rivets out, then drilled the welds and took a cold chisel and used it and a hammer to separate the pieces. OK, one problem solved, the next one was that the TV bracket obstructed the antenna connector on the TV. This I solved by drilling a 1/2” hole through the TV bracket where the antenna connected. Now problem two was solved.

Problem three was that the new mount holes for the TV in the bracket did not line up with the slots in the main support, so the TV would not attach to the main support. Now I was at a little disadvantage. First, I had already screwed the main support to the cabinet, so I did not want to take it out. Second, the motorhome is about four miles from my home/garage where all the heavy duty power tools are. So, after making a trip back home to get big drill bits, I drilled two holes in the main support where the bolts from the bracket would go. This allowed the TV bracket to mount on the main support “as designed.”
Things looked good, until I discovered that the main support also covered the antenna connector. All the other connectors were free and clear, except the TV connector. Back to the drill, another hole, closer to ¾” was made in the main support to allow the antenna cable through to the connector.
So, I then aligned the bottom holes of the bracket with the holes in the main support, put in two screws, attached the power cable, and I was ready to test. To make sure that I did not have a viewing angle problem, I spaced the top of the TV bracket away from the TV with some washers. This gave the TV a downward tilt.

So, now I have to put some trim along the edges of the cabinet to hide the opening that was not covered by the TV. I think that I have some stock left over from the kitchen remodel of the S&B that matches pretty closely to the finish on the motorhome cabinets.

Cost wise – the mount cost about 2/3rds the cost of the TV.  Would I go the same route in the future (using the “factory”) mount?  Maybe. One thing for sure, it was nice having steel components that for the most part fit right out of the box. This in itself reduced fabrication time.

I’ll post pictures with the trim in place when I complete it. Be a couple weeks as work will be getting in the way of play and travel.

Photo one – Adapter – 200x100 to 100x100 mount
Photo two – TV bracket, attached. Lower hook removed and hole for antenna cable
Photo three – Main support with holes drilled to accommodate upper bracket mounting bolts and antenna cable
Photo four -  Semi complete
Photo five – TV installed – gap around edges

Part four will be the finished – with trim result.

John Canfield:
Good job.  With just a little trim, you're done!

Scott-0168:

I saw a cool TV retro while in Florida this year. This owner of a HR mounted his flat screen under the cabinet like the one pictured above. He mounted the TV on a custom made mounting plate. Then with custom made hinges he attached it to the over head cabinet and Plate. The TV would swing up, screen first against the cabinet when traveling. he used snap latches to hold it in place while in the up/storage position.
Sorry no pictures taken!  :-[
