Damn I get tired of this question. Why? Because it is not an option I could buy from the dealer. The same reason people buy Cadillacs instead of Smart Cars, although I do have a Smart Car. The same reason some folks buy AWD instead of two wheel drive. You can drive all them but if you want something special you pay for the options and when options aren't available you go after market. I wanted this motorhome and I wanted gas. If they would have offered an air bag option I would have purchased it. The price was right. I have now exactly what I want that drives and rides great and a lot cheaper than a DP if I could get one at 31 feet which is the max I can handle and still park in my driveways at home and cottage. The original coach was drivable but not as comfortable as it is now. Now does that make sense? I think I have answered this question from you before? You got me.
