I have just recently installed a Rivco hitch. Everything went like the directions said. The bars that go to a brace under the seat are a pain to get in, but they will fit. The isolator wiring for the trailer is a 5 wire system. I have built a home made trailer with a 4 wire system. You will have to go to U-haul and buy an adapter if this happens in your setup. The adapter only costs about $18. I have not pulled with it yet, but it seems very sturdy. Hal does sell it.
