You wouldn't put dirt in the midgate part.....And you can put a 4x8 sheet in the back without the midgate down and it doesn't hang over the tailgate.
And to remove the back window and put the midgate down can be less then 1 minute worth of work, no big deal for something that doesn't get used very much. It was really nice to haul 2x10x12's.....can't do that to well in a Tahoe without taking a lot of time moving seats around and covering stuff with blankets to save the interior
