Both the Rear View Safety Backup Camera System # RVS-770613-NM and iRV RV Stereo # IRV64FR will work to replace your broken systems. The camera will be a fairly straightforward replacement, but for the stereo you will need a 6-11/16" wide x 3-15/16" tall x 6-11/16" deep cutout. I'm not sure what the cutout for your old Alpine is right now. If you can let me know I would be happy to see if there is a better fit available. view full answer...
If you have the 6-pin connector (see attached) then what you need is the Advent Air 13,500 Btu AC Unit which comes in White # ACDOM135 or Black # ACDOM135B. Either of these should plug right into your Dometic Duo Therm setup which means you can still use your current wiring setup and you don't have to change anything else - just the AC unit! view full answer...
