Mackey Motors LLC in Santee sells consignment recreational vehicles — Class A motorhomes, teardrop campers, and toy haulers — from its North Magnolia Avenue lot. The on-site service department handles RV electrical, plumbing, and roof-seal work, a maintenance scope that complements the heavy-vehicle alignment and suspension capabilities at East County Alignment & Brake on Woodside Avenue. Inventory rotates through Forest River, Keystone, Winnebago, and Ford chassis platforms alongside a curated selection of pre-owned passenger vehicles. Tow-vehicle owners upgrading hitches or wiring harnesses source components from the Prospect Avenue auto corridor, including Autoworks Parts at the same industrial intersection. The service bay performs full roof-membrane reseals, awning-motor replacements, and 120V shore-power circuit diagnostics on coaches measuring up to 45 feet in length.
