Linda, I highly recommend the ReadyBrute Elite towbars with built-in ReadyBrake. The towbars are rated at 8000 lbs. The ReadyBrake is simple to install, very effective, and as near foolproof as anything I know of. I saved several hundred dollars with this combo.
I bought the Roadmaster baseplate because it is almost invisible on the vehicle when not used for towing.
I also installed the Ultraguard solid rubber flap on the rear of the MH, and the Protect-a-Tow shield between the MH and the toad. I feel that gives the maximum possible protection for the toad.
Good luck, happy trails, and God bless!
