Does your wife's blazer have a hidden or reese hitch? If so you can get a game carrier or better yet have one made to fit the hitch pretty reasonably. Now if you need a way to get in to the woods from where you park. Do you own or can borrow a mountain bike? If so strap the bike onto the game carrier and off to the woods you go. Getting the animal out a plastic sled from wally world or golf bag cart adapted would most likely be all you need. This is the cheap version.

Of course either buying the ATV/Trailer or a truck would also work.
