Yes, did that too. Just last weekend, found a 15" RCA LED, LCD TV with HD etc,etc, to replace the 15" LCD that I had in the trailer. Why you may ask, well, we only dry camp and the new RCA requires only 2 amps of power versus the 4 amps of the old unit, plus it has a much better quality picture. On a side note, I did see the RCA in 19" and 22" with built in DVD players and 12 volt input (still) with 4 amp power requirement. Since having the trailer, I always keep an eye open for TV's with a 12 volt input (drives my wife crazy), and I have to say RCA has the largest selection I have seen so far. By the way, the new TV was $99.00 at London Drugs here in Vancouver.
