Every spare tire carrier thread should mention Jim's custom made one. Swing-out is the way to go.
Some of his comments:
.......I did a back-of-envelope sketch with a few critical dimensions, and spent a morning at a local welding shop. Later also made two trips to the community college welding class (shoulda started there, I think). Wound up costing me about $225, IIRC, including paint and tire cover.
I had to make one up because no one but RT offered a carrier for the Express van at the time, except a generic hitch mount that blocked both rear doors. By the time I paid dealer markup on the RT item, it woulda been too costy for something that I found so .... errrr...'unattractive'...
Note to anyone copying it: If doing it again, I'd make the hinge point 3" further to the left, so the swing-out would be further / wider by 6". The photos, IIRC, were taken before we added two 1/2" stiffening ribs to the upright, and a second bolt to help hold it shut.
