Well I want comfort, since most of the driving will be done on the street, 18" isn't wide enough for my shoulders. my wife found an extra wide cot at walmart one time, was all excited. I said,"really? hold it up to my back", both shoulders hung off the sides. I'm not a football player or anything, but not small either. I hate feeling pinched.

what do I do for seatbelts then if I don't want to use these? that's crazy that guys just replace them every 2 years.
