Well, the Sarge is a frickin beast. It does have some limitations, like the wheel base, but this dude will take a flogging.
I beat on this thing hard this weekend. Slammed the tranny skid and rear driveshaft multiple times, bent a rear link bar, crushed all 4 doors, and broke another mirror housing.
Still having issues with cooling. It didn't overheat, but did get up around 210 a couple times with the A/C off and with it on. Both were under load going up hill. Same as before.
I must say, for being on half ton axles, this rig is awesome. After watching the rock bouncers get airborn and hearing those screaming V8's, there may be an engine upgrade in the future. Axles and cage are first though. Did get on one spot where I had to be winched to keep from rolling.
