So this year we want to replace the tv in our rv does it need to be a special kind because of the bumps in the roads or can we just go to a big box store and buy one
Lots of good advice. The modern LED TVs are so much smaller and lighter you don't have to mount them where the old CRT TV was. I didn't like where mine was so I mounted the new TV on the wall between the cab and the coach and used a swing arm so I could position it to face the observer rather than having it fixed. It also used a 12v adapter so I wired it to the 12v system.
