Can't specify brand but I used wired side view cameras because wiring was not that difficult and they have a steady picture. I didn't go wild on my wireless set up for the back but mine was on a 37' pushed so a shorter MH the signal would seem to work better. Mine drops out for a second or two every few minutes!
Everything I bought came from Amazon.
