This crane is really over kill as far as the capacity for the back of the 1872, its what I use in the back of the truck so I didn't have to spend anything for this add on. I have some manual outriggers on order, I'm afraid to pick up much weight without them so I havnt done a real weight test yet. I'm thinking it will work out ok.
