You should several replies to your question. Lots of people here have changed their older tv, with the new ones. Yours should have some type of front wooden casing that would have to be removed. Mine have four screws (one in each corner) that allows you access to the TV. Mine also has a panel that can be removed in the front right cabinet next to the tv, that allows me access to all the wires. I also have a panel on the back that faces the front windshield. I have removed it, but did not pay much attention what I can access there. It appears that this can be a DIY project remembering all the posts here and other sites, I watch. I'm not pushing you away from here because you can get a lot of good info, but the County Coach Yahoo site, has good info also. there are people who have taken and posted pictures of their TV removal and installation.
