South Coast RV in Chula Vista has operated the largest recreational-vehicle parts retail store and service center in the South Bay from its Broadway and K Street location since 1997. The service department repairs motorhomes, travel trailers, and fifth wheels from all manufacturers, stocking Dometic, Onan, Norcold, Furrion, and LCI Lippert components — the same broad trailer ecosystem served by Del Amo Motorsports of South Bay on the sales side. South Coast RV installs rooftop and portable solar-panel arrays, Onan generator service kits, and Dometic A/C units, covering the full off-grid power chain for boondocking setups. Hitch fabrication, tow-bar mounting, brake-controller wiring, and supplemental braking-system installation round out the towing-readiness program. South Coast RV coordinates disabled-rig intake by scheduling heavy-tow pickup through Angelo's Towing Chula Vista, which runs flatbed and wheel-lift equipment rated for Class A motorhomes and loaded fifth wheels. The center's highest-tier service involves full rubber-roof EPDM membrane replacements, black-water tank extraction and fiberglass re-lamination, and Onan QG 5500 generator head rebuilds.
