unfortunately the search engines are useless now tom. I use AI when i'm working on my old truck. It's pretty amazing what info you can get from it in regards to wiring
i guess i'm getting old at 39 7/8 but i like the comfort of my L5P. My 06 needs injectors and i dont have 3500 to spend so it will sit for awhile. I say do both
i had PY0's with 285/75-16 and kryptonite Never had issues rubbing. I liked the serviceability of the Kryptonite. The bigger tires eat up ball joints. I'm surprised you got that much mileage out of them.
