Here is an 1800 on an E53

Not sure about the other setups but the guidelines for the box state to place the crossbars as far away from each other as possible. That-coupled with the rear opening clearance-places the front bar about as far forward as it can be. I find mine is super quiet-the bars make more noise than the box.

As for roadtrips-this thing is the best. For a beach trip all the chairs, umbrellas, kids toys, strollers, pack and plays, towels, and anything else that is going to get grungy go up there and get hosed off when you get home. The inside of the car is reserved for important stuff--like wine.
