I have used three different model year Jeep Grand Cherokees as tow cars for
over 35 years. Nelson Funston (JN) is a tire and trailer expert with big heavy
trailers. With my first Jeep, told me to do three things in following order:
-Move some weight forward,-stiffer sidewall trailer tires at max pressure,
-vehicle tires at max pressure. Ancillary advice, maintain Jeep shocks... We
have some interstate speeds of 80 mph in Idaho. No sway!! All my Jeeps were
the 8cyl model so heavier than the old 4cyl and most currently available 6cly
on the road. Also all had 4 wheel drive and the off road accessory that has
different suspension and road clearance. Boise Pilot




Look out when moving trailer weight forward... Never exceed the maximum
tongue weight! Jim

Also tighten up the hitch in the receiver with one of these: they take out
the slop that can add to sway, and quiet down the rig

I found once I stopped towing with a Jeep Grand Cherokee I had no more sway
problems.

Anyone that wants to hear more from Nelson Funston can download his OSTIV paper on
trailer stability he

Anybody convert that model to a nice Excel spreadsheet?

About 8 years ago, I talked to Nelson about using the code; problem was, it was
written in an old version of FORTRAN (IIRC) that hadn't been supported for a long
time, and he didn't know any way to easily ["easily" being the important word]
convert to something that was supported. I've sent you an email with his email
address, so you can discuss it with him. I'd like be able to run it, too.
