any advice for a stupid person (me)lol hooking up to a trailer ball

A convex mirror on the back drivers side of the MH. Delivery trucks in bad neighborhoods have them so they can see if someone is lurking behind their trucks. OR a much better back up camera, perhaps not Bluetooth would work better. My friend, when he's hitching up his car to the MH, drives the car to hitch up, not the motor home. This isn't your fault, or your DH. It's a difficult task. I'm a TT person myself but hope this helps.
