Offsetting your wheels will certainly sling more road debris and mud and snow on your truck..Some folks like that.. The rims my truck came with were offset,,,was happy to get rid of those mudslingers.
Business Plan. How 'bout a drive through mud bay where you can pull in, have mud sprayed all over the truck for that beefy off road look. Deluxe treatment could include some chunks of sod,,maybe some sticks and stones. All this without having to beat the hell out of the truck..
