If you fold down the passenger front and rear seat and take of thee headrests, you can get a slew of 2x4x8's in the X3 with the back gate fully closed. I just hauled 12 last week with plenty of room to spare. Just be careful of the leather! Now, if 4x8 foot sheets of drywall fit, I'd be set.ICEBERG said:I wil be building my rear deck pretty soon. From the looks of it i will have no problems carrying 2x4's.
