Wondering if my rear shcoks are blown, as for the last few months, if I hit a road inconsistancy, like an uneven cattleguard, the back end bottoms out with us all inside - that's about 375 lbs of adult up front, 100 lbs of kid in the middle and 85 lbs of kid in the back. Seems others don't have problems w/6 adults, and I know some others here have reported blown seals.
