Gathering that information, very quickly raised "red" flags as to what setup was an accident looking for a place to happen, and what on a small scale was still a mystery.

We documented, "and proved," the cause of 90 percent of those accidents.

I will look in my very old records to see if I can find the original 12 questions that were used in each and every one of those losses.

However, posting them today, in this forums, would probably cause a rash of arguments, that I do not wish to start.

Perhaps I could post them as an article in our web site, for everyones perusal.

I believe that you'd have done the RV community a signal service by posting such at Inland RV Center's website.

Question Hensely Arrow Hitch

Nick:

Thanks for you analysis. It is quite impressive.

I have a new 28 ft. and use a Hensley Arrow Hitch, and have been wondering how this mechanical contraption (a parallelogram with pinned connections at the corners) functions as a antisway device. It uses tension bars for load leveling.

How do you feel about applying your spreadsheet calculator to an Arrow Hitch?

Some of what you may be looking for is here:

I'm working my way through my non-A/S all-aluminum trailer with the help of others here (great help!)

By the way, SRW, I was wondering if there were a good lunch spot (table service) in your hometown where I can park this 61' rig. I don't often run I-35 through Georgetown, but occasionally do between Dallas and Corpus Christi.

Thanks

SRW, I have very little detailed knowledge of this hitch, but I know of no reason why the calculator should not work if the WD part of the hitch is of normal design.
Nick.

Thanks for the info.

Are you talking about an 18 wheeler?

Let me know and I will check.

Nick - Superior Work!!!!

Wish I could have found this a month ago to help me - but after speaking with TONS of folks (to include Pro Pride & Hensley folks) and figuring out a formula - I get the same results...

Thanks to one of our fellow Airstream members who is also a Tourareg members...

Well - actually your formula is superior but I'm close (faulting a bit on the cautious side)....

See - all this time latter and your hard work is still helping out others!!!
