Looking for a good wireless camera for the back of my 38' fifth wheel RV. Any suggestions? I have read that some are not compatible with the Bluetooth in my pickup. I don't mind spending some $$ on this as long as I "do it right" the first time. Any advise would be great. My family and I live in a rural area and travel short distances ( 100 mi or less) to camp. I tow either a small enclosed trailer or boat behind the fifthwheel occasionally when we go. Yes we live in a state where it is legal. Thanks for any advise
