I wouldn't worry too much about the tow. RealRedSammi pulled his rig from Buffalo, NY to Zuwharrie, NC last summer, and he'll probably do it again this spring if we don't get another spot on my trailer. It wandered a bit behind his Blazer, sittin' on 35's and all, but it was OK. If anything I think the larger tires help steady the flat towed rig. Oh, and just take off your drive shaft to flat tow, you don't have to have it in 2nd and start it a bunch of times.
