Well, currently we are using a Furrioun 12V TV/DVD combo because it was mobile rated. You can't just buy any TV/DVD combo because the DVD does't last long with the vibration.
We were using sky worth for a while (which was Marine based) but I think they kept running us short. So we're now using the Furrion. I met with the owner of the company this week and took at look at their engineering and testing facility. Pretty cools stuff coming from them that is geared towards RV's.
