I have recently purchased a fifth wheel trailer and need to replace the TV....is it essential to purchase a Jensen for RV's or can I go out and buy the most economical I can find?
The Jensens and the rest of the 12c DC TV's are junk. They are bottom of the heap Chinese sets that are re-branded as Jensen, Skyworth, Polaroid, etc.
Better to buy a 110 AC TV that is a top tier brand like Panasonic or Toshiba or Samsung and use an inverter if needed. With the smaller sets there is often a brick and the set can be run off 12v DC with an adapter.
