Thought some folks might looking at this latest install.
I helped 'ole Calvin install a 42" LG LCD LED TV in his '06, 40' Tiffin Allegro Bus.
The coach had a factory installed 32" HD TV. It did not have a digital tuner. It therefore required the add-on tuner for "Local" digital signal Winegard bat-wing reception. Besides he wanted a "Bigger- is better" TV.
Sorry for the focus problem- Here is the "Hole" for the new TV. Notice the oval shaped hole in the back part of the case. That allowed cooling air into the original TV. That won't be required for that use anymore since the new TV is mounted on the exterior of the TV housing- But we will use that hand hole later for securing the new TV.
Ahhh- Better focus- There, conveniently located was a structual piece of angle iron (black) supporting the front cap. Two holes drilled into this angle iron, with thru bolts and washers, now support the upper end of the new mounting piece of 2x4. The bottom is attached to the existing floor of the cabinet with 1" angle aluminum pieces. The sides of the 2x4 are strenghten by the use of more angle aluminum screwed into the sides and back of the wooden bracket.
We then attached a 42", three pivot, mounting bracket to the rear of the TV.
We have 1/2" clearance on each side of the new 42" TV for the upper cabinet doors to open and close.
New TV in it's new mounted position.
Notice the two shinny angle brackets that slip into two studs mounted on the floor of the cabinet. These stud bolts are mounted into a threated 1/4" plate of aluminum. When the TV is gently pushed back to locate and center itself, two wing nuts and washers, are torqued from behind- through the old, large oval cooling hole. These "L" shaped brackets screw onto the new "TV's stand" mounting holes.
We looked at putting in a 47" TV but the upper cabinet doors would not have cleared the TV.
Now Calvin has to have the King Dome modified to catch the Dish Network's 129 HD Satellite.
