Like PJGMG, I just installed a Blue Ox base plate on our 1999 Jeep Cherokee 4x4 and bought a Ready Brute Elite Towbar with the integrated Ready Brake system. I really like the fact that I don't have anything to put in and take out of the toad floorboard every time we tow, which is often. The tow bar is extremely beefy, looks great and has a lifetime warranty.
We got the whole package that includes the base plate, towbar, safety cables, towbar cover, breakaway kit, indicator light for the motorhome, 6 wire coiled wire connector... I think that is everything. We bought it from www.TowbarsUnlimited.com
