i would never put a deer inside the cab covered or not. the ticks and chiggers that abandon ship will end up with a new home in your blazer. that small blazer is so poopular i would go to the junk yard and get a used hitch for it and then get a hitch hauler for the back. my buddy just recently got a used hitch from the junk yard for his gmc blazer for 20$. a deer hauler carrier you will probably use the rest of your life and ive seen them new for 50$. check harbor freight. i believe you can also just buy the carrier frame and add a piece of wood for a base.
