You can fit 35's on factory wheels WITHOUT any trimming. Hell there are guys on here that have ran 35's at factory height.
OP I had good luck with the 295/65R20 with leveling kits. Really just pick what you want and go with it. Some guys have a slight rubbing on the frame with a 12.5" wide tire though FYI.
Gotta call BS on running 35’s at stock height with no rubbing issues. Confirmed by my buddy who is the store manager at the local Les Schwab tire shop ... who started laughing when I showed him this post. He puts on hundreds of leveling kits and recommends no larger than 33’s or 34’s, which also depends on the wheel offset, width, etc.
Also, my 2019 3500HD and my father’s 2017 3500HD both had front ends that were over 3 inches higher in front than the rear in stock form. My father was able to turn the stock keys up all the way (2.75 inches of lift) and install Toyo 285/75R18’s (35’s) on stock wheels and experience very minimal rubbing ... that only occurred at full turn and at full suspension compression ... but it still rubbed. Admittedly my aftermarket wheels having a +18 offset vs the factory +44? (stick out ~ 1 inch further than stock) required more cutting of the wheel well liner both front and rear ... even though I was also only running 285/75R18 (34.8”x11.2”). In fact, I even had to trim a little metal on the fender behind the wheel well liner ... and that was with lifting the front 3 inches.
But like you said, should do what he feels is best ... just trying to advise against some of the pitfalls I experienced first-hand with leveling and 35’s.
Side Note: Can’t express enough how much better my truck rides with a 4 inch suspension lift kit. I personally did not want a lift kit ... because I did not want to lift the back of my truck for towing reasons. After breaking ties rods because of leveling over 2.5 inches ... gave up and went with the 4 inch lift kit. Got my “Cowboy Cadillac” back ... regarding the plush ride of a suspension lift kit vs the harsh ride of a leveling kit. But I learned the hard way ... after two leveling kits ...
