Nice! 48” rear swing doors. The bulkhead will be removed for a full pass thru, and then repositioned horizontal for a bed platform in the rear.Sweet! I bought one on a 2006 GMC 1-ton chassis about a year ago. So much potential! Those ladder racks howled at speed so I cut mine off. Yours have ambulance doors or a roll-up? Pass-thru cabin door? Looking forward to your build!
