I had a 3" Rough Country set up on my '08. I don't have the truck anymore, but I really liked the look. I had 275/60/20s (33x11" bc they were cheap). I loved the size, not too big and not stock.
If I had a nnbs again (I have a nbs now), I would do the 4" BDS with 33"x12.5 toyo MTs. I wouldn't do the RC 3.5 (no longer 3") because of the alignment issues. BDS makes a great kit.
You will not need to re-gear with 33's (or even 35s really), so that can save you some $.
Not sure what my fender measurements were. I will search some other forums.
Here are some crappy pics, I will search for better pics. Ultimately, it is your truck and money (as srtluvr said) so do why makes you (and your wife) happy.
Before any debadging.
Edit: found more pics!
These were before Adams :blush: Look at those gorgeous wheel wells! :facepalm:
