Our backup camera has died. any recommendations for a replacement? We definitely want wireless.

I have the Firrion wireless observation camera and it has worked great. Camera is tied in to the marker lights. Also have the booster in the battery bay. Never tried it without the booster as it came as a package.
Firrion has 2 cameras do not get the backup version

Furrion

I concur with Shane. Mine works fine without the booster. Here it is on Amazon: Furrion FOS48TA-BL RV Digital Wireless Observation System (Camera + Monitor) https://www.amazon.com/dp/B017P8H7BO?ref=yo_pop_ma_swf

Here is my plan , I am getting a Rand McNally overdryv 7 RV GPs (cost $399) and I have a sony wireless camara from dieselboss that cost $299 as a wireless kit. I didn't want the dash of the truck all covered with different systems.They also have a tire pressure monitoring kit , not sure if that can be intergrated like the back up cam? Right now the redwood is sleeping in NH at the snowmobile camp and I plan on pulling it home in the next two weeks so I hope to have the kit installed before the end of the month.

my second choice : https://www.tadibrothers.com/products/7-wireless-ultimate-rv-backup-camera-system

this kit in the end may work better but at a much higher cost!
