I've got one available. 4x4 with 8-inch wheels. Box big enough for two sets of wheels or one set and tools, jack, etc. Enclosed, lockable, everything stays hidden inside and (mostly) dry. Not 100% waterproof but rain doesn't poor in, either. I've got pictures but the hosting site is blocked from here at work. I can send them to you this evening if interested. Pulled all over the midwest with an MR2 and never had any problems. Located in Kansas City, MO. Probably out of your range unless your going to Nationals next week.
