Hi Ken,
You probably are not going to get too many responses to this on this forum. This particular forum is oriented to small lightweight fiberglass trailers.
You might try posting your issues over on rv dot net.....there is a huge amount of information about Hensley hitches there.
All I can tell ya is that a Hensley in the driveway is worth two in the bush
If I were you, I would contact the folks at Hensley about it. From everything I have heard, they are generally very helpful in getting things squared away when there is a problem. For what those things cost, they should be helpful !
Good luck with it. Also, another forum that has a lot of experience with them is the Airstream forum ( airforums dot com ).
Hi: Kenorie...We camped nextdoor to an Airstream with a Hensley hitch. I thought our Husky EZRoller 16K fifth wh. hitch was big and fancy? Fact is "When she's broke she's broke". "When We're hitched we're gone"!!!
