3500 with the 6.0, thats the ticket! We searched and searched for a 2500 or a 3500, white high top, the only thing I could find was a 1500, seems most HTs were on 1500 chassis. Kept a cruiser look, all the fab shops I went to didnt want to work on the build. If you couldnt bolt it on, they didnt want to touch it. The 1500 dosent cut it, I put a heavy duty break system and airlift. Its really tricked out inside.
