Thanks for the input Trek420.

My concern is that I really want to have room in the car or truck for a cooler , backpacks etc etc. I was thinking about a roof rack for the truck and one trunk bike rack to use on both vehicles ...but I really dont know how hard it is to mount the bikes on top of the roof . My kids have mountain bikes and I have a steel road bike for now (pretty heavy ). We sometimes invite a cousin or a friend to bike ride with us.
