The rear seats are folded down. 65 gallons of water with an additional 50 pounds still weighs less than 600 pounds. You put 3 adult people in the back and its about the same weight. I use to haul the same exact stuff in my stock 1997 subaru wagon with no problems with bottoming! I had to retire the old girl, so I gave it to my niece. I bought the X because it is actually built on a truck frame and figured it would haul it no problem. So upgrading to a larger vehicle is out of the question. Gotta find a fix for this one. Any info on airbags?
