I don't plan on rock crawling in this truck at all, though I will be doing a fair amount of light trail use. Not a grocery getter by any means

The OEM wheels are 18", but the tires are as much as 20"

I want a wider stance, so a 4.5" backspace on a 10" wheel is what I want.
Though, the bigger the wheel.... the smaller the sidewall

I agree about the leveling kits, but I will also be adding a Pro Comp 1.5" add-a-leaf within a month or two. They're pretty low cost.
