The reason twenty-nine feet is such a common length for RVs, I presume, is that once a vehicle gets much longer, you need a special permit to drive it. That would mean forms and fees, possibly even background checks. But show up at any RV joint with your thigh stumps lashed to a skateboard, crazily waving your hooks-for-hands, screaming you want that twenty-nine-footer out back for a trip you ain't sayin' where, and all they want to know is: Credit or debit, tiny sir?
