I have a giant, unruly, impractical garden. Every spring I make 3-4 trips to Lowes/Home Depot to buy composted steer manure. I owned an X5 until 18 months ago, and I could easily fit 54 bags (2 cu yds) of manure in the back with the rear seats folded down: The X5 died a premature death (e.g. before Model X was released) so I bought an RX450h instead. It also fits 54 bags of manure, albeit slightly tighter: Has anyone here attempted to load up a Model X with 1 cu ft bags of manure/soil/???? How many bags can you fit? The front passenger seat is off-limits, because my son/Sherpa needs to sit there. Also, how is the ground clearance on the X5 relative to other mid-size SUVs like an X5 or Lexus RX? The trail down to my garden isn't too hazardous, but it is a dirt path with some grade, some erosion, and some rocks. Thanks!
