Which airport? We are north of Houston Intercontinental (about 15 Miles) and we store (covered) our Motorhome in a very nice Uhaul lot on I-45 North. Good neighborhood and great security (couple lives on site). Just a hop, skip, and jump from the airport on the Hardy Toll Road probably no more than 20 minutes. Unfortunately I don't know of any storage lots closer and, frankly, the airport is not in the best part of Houston.
