No crack = wheeling mah-sheen?
Whatever, I love it when a man tries to tell me why smaller is better. I have heard the small = less damage story before.
Big = more fun.
If you are going to mod your truck for wheeling, you might as well do what you can to it. Phil, Ken and a few others that have them lifted and wheel them are pretty much pioneering in this area so things will need to be worked out until perfection is reached. There will always be damage- even to the biggest fabricated rock crawling buggy. Everyone pays a price for wheeling their truck and pays more for how much and how hard.
