I'm looking for any ideas for building a rear bumper with a swingaway wheel carrier for a sidekick. I'm going to run 31's or 32's and fitting the spare will be an issue. I was thinking of doing something so that I could turn the rear bumper into an air reservoir for my compressor to inflate tires quicker and use it to blow dust out of the filter etc. Anybody got any pics or plans or suggestions on materials to use that would give me a starting point?
