Found some old references to the 19 inch RCA model online, curious if anyone has the 22 TV/DVD combo. Not many reviews online, but the specs have superb viewing angles of 160 degrees or better plus 5 watt speakers for decent sound. Good comments on the long-haul trucker forums.
I also found this interesting mount that locks in position for travel better than the few I've seen. A bit on the spendy side though. Short video on it.
Here's a really nice lock down mount for our 21 - I'm having the wall next to the nightstand reinforced to hold it. Can also be easily moved to a 2nd mounting plate.
