toolster-
According to both the
brochure and
owner's manual for your coach, it came with a rear-view system with either one or three cameras and a display in the dash. It looks as if the manufacturer was Weldex.
This means there's already a wire between front and rear of your coach- assuming no one has ripped it out.
You may want to call Tim at RVCams (link
here) and discuss upgrade options with him. I found him very helpful when discussing changes to our coach's rear-view system.
Wireless cameras frequently have more problems with reliable service than wired cameras.
