Thanks or all the input. I was reviewing the yakima site and saw the hitch class recommendations in the product description. However some of the hitch racks for 4 bikes show comparability with a class 1, but I wouldn't want to put 4 bikes on.

I'll probably go the class 3 route, it just seems that for certain cars class 2 was the highest rated receiver available.
I do like pickups, but our family wants to balance a smaller vehicle as we do mostly city driving with fuel efficiency.
