I bought
this for $15 from Northern Tool. Then used the tongue from a hitch basket I'd already bought (I'd bolted the basket across the front of the truck bed) for the upright and welded a tire carrier to it. I placed it high enough that it clears the hitch when down After mounting it I decided to notch the upright and bend it back toward the truck. just to tuck it in better.
I'm either gonna have to buy one of those anti rattle things or just drill a hole and weld a nut to the hitch and use a bolt to hold it tight.
I like it simply because I can now carry two spares on a trip without losing space in the truck bed and I can still pull the trailer with our camping gear.
