I'll never forget the guy at Allouette Lake who pulled up in his 1 ton with a brand new diesel motor in it, and a 10 foot camper and towing about a 22 foot ski boat.
backed down the ramp, stopped just shy of the water to pull the back straps off, put it in park, still running, got out and started walking to the back of the boat. About 1/2 there there we all heard a loud SNAP as the parking pin broke and the truck slowly backed down the ramp still atatched to the boat and camper. It finally stopped when the floatation of the boat and camper was greater than the weight of the unit. By that time it was up past the side windows of the camper and past the door windows in the truck. In addition he had also hydrauliced his brand new motor ($7000).
It was nice to learn that lesson from someone else's misfortune. Now I always shut off the truck leave it in 4 lo and have the parking brake applied anytime I get out ot the truck on the ramp. [^]
