We just installed a new BEDROOM TV in our 36 RL. No brands of 32” TV would fit into the cabinetry. I found an Insignia 29” that had built in firestick. Bought it from Best Buy for around $200.
We replaced the factor TV, installed a std wall pivoting mount, along with a 32 inch set. Much easier to see:-) As well as allowing you to remove the set for storage for traveling.
I just replaced the bedroom tv in our 36 rl. Bought a 28" LG from best buy. had to lower the wall mount easy peasy what adifference in picture quality.
