I was trying to add a link, but it failed. Here's the link to the link in my thread on my bus, The Silver Snail. The link there works, but the copy and paste that I tried didn't work. So here's an attempt at a copy and paste of the link to my thread!
I'm going to try it out this weekend in the bus. On the back of the TV, it clearly shows DC in. There were several other reviewers that said it was a direct plug in for their RV.
