Gavin, did you mean a 13'6" tall box truck? That's Federal DOT max regulated height, anything over is overheight. Bob, I wasn't getting upset, I laugh my ass off when I see Big Trucks get stuck or chop their tops. It does however piss me off that companies and DOT would allow these wannabe truckers behind the wheel of such a big truck. I'm all about safety behind the wheel, especially in a Big Truck, people's lives are at stake, these things aren't sports cars but I see drivers doing unspeakable things in these vehicles. By far the worst drivers I've witnessed over the years are tri-axle drivers and roll-offs. No respect for other drivers safety or their own. I grew up in the trucking industry with three step-dads that were truckers so I have great respect for "Real Professional Truck Drivers". :driving::supercool:
