Found a 2004 Ford F650 with an 18' ft. body w/barn doors, 108"tall, 102" wide. has 2 rows of e-trac, load dollies, a 72" stand-up sleeper, sleeper has a microwave. Air ride suspension and seats 6.0L turbocharged diesel 230HP @ 2100rpm, w/Allison 2400 4-speed automatic trans. 229,000 miles, GVW 26000. Would this be considered a "C" unit and would many companies be interesed in putting it on. Would they be more interested in a 22-24' box? Also does anyone any input on the Ford 6.0L engine, just wondering about the reliability and pulling power. Price is about $27000, but is negotible. Any info would be appreciated. Thanks, Tom.
