Beef up the transfer case maybe? Is that possible?
Hooking on dry pavement and spinning wet sounds good to me! Your tires aren't very big! My Bonnie tires are almost that size, stock. It'* weird seeing those trucks out there, full size and all, that have like 15s or somethin on them. Looks real goofy.
I think it'* awesome to slide my '79 shortbed Chevy! I went out on the dirt roads today and was goin like 35, like I normally do in my car. With a truck, it'* totally different! Sliding all over the pace, scared as ****! God was that a rush!
