The dump body is off the truck so if your only removing the hoist now you are OK with your engine hoist. The hoist only weights about 1000 lbs or so and if your engine hoist won't handle that it isn't mush of a shop crane. You'll know before you get the truck out from under it. Another option is to jack it up off the frame and put 4x4 lumber under it from and rear setting on top of barrels, then drive the truck out. I've changed 26' moving vans this way when I first started in the truck equipment business. Necessity is the mother of invention as they say. No money, few tools but lots of need, just be careful and think it thru first.
