Bite the bullet one time and buy you a airsafe 25k hitch.It fits on regular Reese rails. I bought my first 5th wheel and hitch in august 2006.Till then I had a cabover camper for 23 years. So I knew nothing about 5th wheel hitches.I called a friend who had a 5th wheel all those years for advice on a hitch. He had a regular Reese hitch all those years till January that year. He bought the airsafe 25k hitch. His exact words to me was. I am not saying it is worth the money but I like the ride. He pulls a center console boat behind his 5th wheel . He said he left the lake and forgot a soap bottle on the kitchen counter. It is a 2 hour run from the lake to the house. He said when he got home the soap bottle was still sitting on the kitchen counter where he left it. That is all I needed to hear. I had enough money to do things right the first time. Not buy a starter hitch then upgrade later. I have not regretted buying the airsafe 25k hitch. The reason for the 25K instead of say a 16k hitch . Is the 25k comes with the binkley holland head.
Also with this hitch the truck and 5th wheel are not in a bind. The trailer just floats behind the truck. Their are other good air hitches on the market. But a air hitch is the way to go.
