thank you very much for the insight!

mostly my question was about the aerodynamics of the trailer/canoe/jeep combo. last year my brother drove (hes a bit of a lead-foot) and didnt want to drive in the 'sweet spot' where it goes about 60 and never downshifts.

as for the border search, my group is actually very well mannered. we are very respectful and answer their questions with proper answers. we do everything right, its just that we are 20 year olds and the time we cross is kind of suspicious or they are really bored or something.
