I agree with davitk to get an old 4x4 and take the bed off and build a stake body. The last (and only) bed I took off was only held on by four bolts. It was on an old 65 Chevy. My 98 Dodge came from the factory with the bed cocked to one side and it appeared to be only four bolts too. The dealer fixed that. You can take a bed off in an hour and once off, I would think you could construct a stake body for very little more cash.
If you are considering a Gator, for less money, you could consider a small 4x4 with a homemade stake body. It would haul more, be less expensive to maintain (Parts), and you would have a more comfortable cab. It would also be more heavy duty in design. Unless you have really steep land the truck would probably go almost any where the Gator would go. Around here, S. GA., you could pick up a small 4x4 and convert it for a LOT less than you can buy a Gator.
There are Christmas tree farms all around my place in NC and I believe a stake body would be much more usefull for that purpose. If you go this route there are kits that you can buy that make the stake body or regular bed dump. But, they are kind of pricey (around 2,000) unless you determine you really need it.
With the homemade stake body you could probably build a pivot for the back of the stake body and build a mount that rises three or four feet above the bed, in the front, and attach a small winch. The winch would lift the front and tilt the bed. For occasional use that would probably work well and add only two or three hundred to the cost of the bed.
