There is a MH service center near me that has storage available. Integrity RV Service Center, 4411 Bankhead Highway (US Hwy 278), Douglasville, GA 30134 - Phone 770-793-1186 http://www.integrityrvservice.com/
The storage area is at the bottom of the photo. At one time was John Bleakley RV sales (a long time Ford dealer) but they closed the sales office when the recession hit. These guys seem to have a good reputation for RV service, mainly MH's. They can winterize it for you, it does freeze here in winter. Hartsfield Airport is about 15 miles, easy access from the West side, limited traffic. Service center is not far from Thornton road which if taken southbound goes directly into the airport, changes names a couple times.
