My '02 Journey has several screws coming up from underneath holding a plastic and wood cover on the bottom of the steel TV cabinet. When I bought the RV that old CRT TV had been replaced by a Vizio 32" flat screen and there wasn't any surround around the front of the TV...guess the remodel eliminate it. I can see evidence they removed some woodwork from that cover for a more finished appearance. The TV just fits between the left and right cabinet doors with 1/2" free space on each side.
They shaped an aluminum bar as a handle and bolted it to the top two mounting holes on the back of the TV. What they did to hold the Vizio was use a ratcheting nylon strap to connect to that aluminum bar on the back top of the TV to the back (front of the RV) wall. Then also drilled holes downward in the plastic base of the TV and used 1/2" bolts and nuts to hold it to the bottom of the steel TV cage. The bolt heads were covered by the original cover that comes up from the bottom.
