Chris is correct. Before we bought a new 1977 Prowler I went used hitch shopping. Ended up at a place that was an Airstream dealer. He had several used set-ups and I bought the heaviest set-up he had. They were used on the Prowler thru 1988 when we bought a new Terry and continued on until 2003 when we went fiver. They have many, many miles on them and were always used to even the weight distribution. Up and down the East coast working on race cars. They would have to be down to about nothing before I looked to replace. They are still in our shed in Yuma, AZ.
