For anyone with the OEM or aftermarket crossbars on their truck, have you run into any entry issues, whether it be a parking garage or home garage, etc? I want to put some on our lincoln navigator, but theres a lot of garages(including my own) and i worry they would contact the ceiling of a pg. Also, are they good at holding extra cargo? My wife wants to put 2 8ft long kayaks on them. Any info would be nice.
