I'm am fascinated by the Hensley twins. I love the design, but it seems that there are several reports of failures with cracks and the sort. Every report I have read has resulted in Hensley taking care of the issue.
I did read the classic thread in the Rv.net archives about the Ha Ha failure in Knoxville about 10 ish years ago. There was allusion that the HAHA failed but no proof presented for sure. Just statements that it was the failure point. I'll try to find the link later since I'm on the old iPhone right now. Maybe this is the thread JJBRISH linked too previously.
I am not opposed to owning a HaHa. Not at all. Any mechanical device can fail...we all need to be reminded of that from time to time.
I did watch the youtube video that JJBRISH alluded too about the constant Hensley bump. It was CONSTANT and happened so much on the video that I wondered if it was faked.
Here is a pic or a Hensley hitch head I actually made an offer on. I figured it was rebuildable.
One of the strut mount holes are ripped out. I can only imagine what happened.
