Came to my wife's job to pick up the X5, and she'd filled it up with 53 boxes (combined weight of +- 1500 Lbs).
Went crazy and got scared to drive it home (the truck was sitting very low, no 3rd row so no self leveling).
Could feel the weight by the way the suspension was working, but the engine, maybe a big .1 MPG more.
I simply
my X5. But just to be in the safe side, the return trip was done w/ a UHaul 4x8 trailer !
