Roof top container successfully and securely installed on the Truckster (aka, the name of the station wagon in National Lampoons Vacation). The Green Truckster is ready for practice road trips before the road trip to Colorado this summer.
Thule roof top container has seventeen cubic feet of storage with a very low wind profile.
Next will be to add a Thule bike rack that attaches to the rear trailer hitch. That way I can carry my Trek 29 incher mountain bike while keeping my Colnago road bike inside the SUV.
