almost seems like they were trying to put the ski in the back door
if this is the case I can see that the truck was proably running and it died when the exhaust was flooded out and starved itself.
I remember years ago when someone let a jeep go under.
not sure if it jumped gear or if it even had the e brake set
I usually leave the truck running, in gear with the e brake on
the 'burban I have now does not have an e'brake on thedrums do to the axles being changed out. makes me nervous everytime
