I understand that this is a great setup for some. Personally I would not want to drive around in a "SmartCar", I like some metal around me. Also don't see why having two rigs with engines and only really drive one while camped. One rig should do everything you want. Any newer 350/3500 will work as a daily driver and tow your load within specs. Also most women would drive the pickups well before the Big Rig.
As far as holding up traffic that has not been an issue with my 33-35K combined load.
Nice to have options!
