Woohoo, just won a year of Elite membership and mine just expired! Anyway, Josh, ya I know I could weld the crack up, but being so big I'd be willing to bet it would just crack again along the edge of the weld really quickly. I've noticed small cracks all over the body over the years but nothing ever that big or worrisome. I know to keep the truck from falling apart eventually it will need a cage with the body tied into it, so maybe that will just happen sooner than I'd planned.
On a similar note, the sliders are really close to the body and touching in a few areas, so now driving over uneven roads or big bumps I can hear the body slamming into them and it's really annoying!
