There is a company called Tadibrothers.com that sells a lot of different styles of backup and observation cameras for RV, trucks, farm equipment, etc. and they also have adaptors that will allow you to mount some of their cameras to the Furrion mount that comes on a lot of the pre-wired trailers. You might want to check them out. Disclaimer....I have not yet purchased any type of observation camera for the new trailer, but I will eventually.....after I get caught up with the other stuff I'm doing.
