Installed a Supersonic 12v 22" tv from WalMart in 2019 at the wife's request. It fit perfectly above the nav station and is completely out of the way. Nothing bigger would fit there. I typically leave it unplugged to keep it from becoming a vampire drain on the system, but when on the LCD uses very few aH. Since its inside the cabin I haven't noticed any issues at all in 2 years with corrosion, etc. It is advertised as "compatible with RVs and boats", though I strongly suspect that is only due to it running off of 12v, and nothing to do with being marinized. Picture quality is very acceptable, and I can plug an iPad or iPhone directly into it to watch Netflix, etc. I run its audio out to the stereo aux and get good sounds from the cabin speakers.
