All I can think of is look for aftermarket stuff.... You know, I know this may sound strange, but if a thief came up to me and told me "last night I was going to break into your RV window and tear out your radio and steal your TV's but thought I'd rather come and ask you for $100 today instead... I think I may just give it to him. I know it sounds crazy, but way more $ and hassle are done after the fact. What could the radio be worth along with the install, and the TV be worth, in comparison to the dash or other things they break.
