I goot ahold of the welder who did my push bar, and he is coming over tomorrow to see if he can come up with an idea for me to be able to carry a full size spare externally. I can't wait to see what he comes up with. I emailed a craigslist add for a welder with my idea, and it turns out it's the guy who did my push bar.
Here's what I sent him...
I found this spare tire carrier that is for a 1 1/4" receiver hitch. I emailed him asking if there was a way to modify it to tilt down when I need to fill up. He said he'd come over tomorrow and figure out something. Says he can fabricate something up without having to modify something that is already built.
I am going to show him the receiver hitch idea and the one picture that Eaglefreek posted of the Wrangler.
I'd love to have something independent of the receiver hitch in case I want to tow a trailer and carry the spare, but not too worried about it, because if I am towing I can carry the spare on the trailer. We'll see what he comes up with.
