Thanks 3B and crenwelge! Its a relief that they are not RH5s. Now only if I had a couple more as spares so I could take them off, clean them up, and still be able to move the truck around. Do they have a specific name or model? I would like to try and find a couple more good ones.
As far as the hoist it only goes up about 60%, so based on the leaks and the fact that it has no doubt been many years since any was added I figured its probably a little low. I am assuming that it is a "gravel bucket" as it definitely wasn't a farm truck. But I have linked to a picture of the dump body below.
