I tried using a wireless remote camera to either hitch up to my PUP or to see while backing up. I never had good reception and prefer to use the hitch balls to hitch up or getting up frequently while backing up my PUP.
Extension cord (30 Amp). I've on case where the CG post was on the passenger side of the PUP and a good distance from the PUP. I was sure glad I had this since it was duing the winter and the the E3 30 amp cord was not long enough.
