An elk farmer close to our place took some old pickup trucks and cut the cabs off and made trailers out of them , cut the springs out and lowered the axle to the frame, he can tow them anywhere in his pastures, water runs out no waste, even works for his bull with antlers, what about smaller versions from old totota or datsun 1/4 ton's for deer???? or you could build a small trailer on wheels that fits a couple small square bales.
