I will not bore you w/all the details of an intensive 3yr+ quest to select the right conversion and installer for me.
I have rode, at length every major conversion, including those we sometimes refer to as "training wheels".
My conclusions:
1. Hannigan
a. IRS that oscillates, not just up/down
b. Differential that is in line w/ the Wings drive shaft, not off set.
c. The "ride" was the best for my wife and I.
d. Fit/finish and color match is unparalleled.
2. EZ steer was a must for me.
3. The installer is as important as the right conversion!
a. Talked to, visited, hung around many.
b. Chose LoneStar, even though I had several much closer to
me.
c. Installer choice has a lot to do with the fit/finish
You must made the choice based on what you like. Check out all you can.
Good luck,
Dawg
