Same here - the car was terrific. Just got back from vacation in which the Explorer was loaded with 3 bikes, cargo box, golf bag and luggage/food stuff. The house we rented was on a private dirt road that was 3.5 miles. Also got to load 7 adults (used the 3rd row seat for the first time) when we went out to dinner - I thought the car would feel very heavy on the dirt road but it was fine.
We used a new Thule Aero Blade rack for one bike and the cargo box, and Thule T2 hitch rack for 2 more bikes. Despite all the stuff on the roof, it was still very quiet with only a wee bit of noise traveling 75-80 mph. More noticeable with the sun roof shade open, barely noticeable with it closed. The Aero Blade is much more quiet than my older style Yakima (round bar) and Thule (square bar) racks, even with a front fairing on those racks.
Also glad to have the Sirius radio, as not much in radio stations and sometimes I get tired of listening to song library on my iPod, even though its quite extensive.
