Webb's RV Supply Inc in Lakeside has operated from the same Maine Avenue location since 1977, providing RV parts, accessories, and repair services to recreational-vehicle owners across East County San Diego. The shop holds designation as an authorized Dometic warranty facility, servicing Dometic, Norcold, and Thetford components that RV owners heading to camping destinations like Lake Jennings rely on for refrigeration, sanitation, and climate control. Repair bays handle converter and inverter diagnostics, water-heater element replacement, slide-out motor service, and LP-gas system leak testing, covering the mechanical systems unique to Class A, Class C, and fifth-wheel platforms. The parts counter stocks replacement awning fabric, roof sealants, leveling blocks, and 12-volt electrical components, reducing the lead time that forces RV owners to wait on mail-order shipments. Lakeside's position along Highway 67 and the I-8 corridor makes the shop a natural staging point for rigs heading east toward El Monte County Park and the Cleveland National Forest campgrounds beyond Alpine. Inverter installations include pure-sine-wave units rated at 2,000 watts continuous and 4,000 watts surge, sized to run residential appliances without the harmonic distortion that damages sensitive electronics aboard modern RVs.
