I'm rebuilding a 99 SLT Durango, I parked it at 365,000 miles both motor and transmission needed new gaskets but still ran. I'm fixing to have the motor rebuilt, it's a 318, I'm having 360 heads on it and an RV cam. I'll also have Jeep JK Dana 44 put under it. I've rebuilt the frontend 4 times since I've had it. I'm building the Durango to tow, not just an RV trailer, but logs. Now, I've been in Crawlers down in Hot Springs but don't know many folks that use them for street use.
