Put a hitch on the front of your truck. Trailers are easy to back when hooked the the front. If its fairly level ground I'm sure a larger 4 wheeler or SXS would get it done also.
This. Way cheaper than a UTV and much more useful. If you don't need a UTV for something else, why spend the shekels? Unless you already have the metal lying around, you can buy a front hitch for not much more than it would cost to build.
