Haha I've got a F-350 CCLB with front and rear bumpers. I've got about 3" of clearance in the front, 1" of clearance in the back (thank goodness for cameras when backing), and currently 1/4" of clearance up top. I can gain an additional 3 1/2" of clearance up top with some work though, which will barely squeeze in some 37s. If my truck didn't stay home all week I wouldn't give a damn about it being in the garage. I'm gone all week for work, and sometimes 2-3 weeks at a time. I like it being parked inside while I'm away.
Oh I agree, if mine could fit, it'd most certainly be in the garage.
