I just made my first road trip in the Box. Coastal NC to Tampa Bay area in 11 hours. Return after two days, also in 11 hours. Became god parents in between! I had a comfortable trip, altho some of you had me worried. My li'l wife seemed okay in pass seat, but probably not quite as comfortable as I. Maybe cuz I got to drive.
BTW - 27.7 mpg from S Carolina gas stop to destination. 26.6 on return with an additional hour of back roads from I-95 to the coast. Cannot divulge average speed based on 5th Amendment!
Also surprised one piece of roller luggage fit in front trunk.
