Sorry so long to reply. I've been kind of off the internet a bunch lately. I don't know anything about 5ver hitches. But, I've been to the last four HDT Rally
rally's. From what I hear there it sounds like ABOUT SZMYT ET PRODUCTS
is the best hitch. I know the designer, Henry, from those rally's and have talked to him a lot. He seems pretty smart about this stuff. I don't think he posts on here. He's on iRV2 Forum | - RV Forum Community and RV News
and you can find him in the hdt sections. I'd call him up or contact him on line to ask about those hitches. Make sure to have some food and beverage handy because he's got tons of knowledge about everything you could ever imagine with a hitch and it might take awhile. Have you posted this question over on irv2? Do that and you'll get Henry going I bet. Might find some others that have used that hitch that could chime in too. Not too many 5th pullers around on this forum.
