Very happy with 10 ply Toyo AT3 in 285 (same height as 33) on my factory Willys rims. Lots of driving in heavy rain lately. Tried GY Assurance street tires before after getting rid of factory mud tires. Toyo hands down is better ride than either of the previous sets. 10 ply was recommended...
One battery. Ditch the Aux battery. My Z71 worked without 2 and the wife's Mercedes works without 2. You have the technology.
Get rid of plastic OEM bumper on all levels.
Inline six (the good old 4.0) or a V8 option
My "required list"... other goodies were vanity or creature comforts. My Willys is a daily driver for work. I left the suspension alone but did move up to the 285/70/17 Toyo Open Road AT 3 10 ply. That was a world of difference in ride and handling. here is the rest:
Undercover Swing Case...
