MDC (Market Direct Campers) builds some of the most capable off-road trailers on US roads - but if you own one, you've probably discovered that getting parts is harder than buying the camper was. MDC USA handles most spares through a parts-request form, which means submitting details, waiting on a quote, and waiting again on shipping. When a water pump quits or a solar controller fails mid-trip, that wait hurts.
This guide covers the MDC parts that most commonly need replacing, what fits across the MDC range, and how to get the right component shipped from the US - fast.
MDC models this guide covers
MDC's US lineup spans tent trailers, hybrids and hard-wall caravans. The most common models on US trails include the XT12HR, XT16HR, XT17HRT, XT19HRT, the Forte 9 and the Robson. The good news for parts: many components across these models are shared, and a lot of them are the same universal, Dometic, Fiamma and ARK parts MDC fits at the factory - which means compatible replacements are readily available in the US.
The MDC parts that wear out first
Off-road campers take a beating. These are the systems where owners most often need spares or upgrades:
Water system
The 12V water pump is usually the first thing to go - they're consumable items rated for a few years of regular use. Faucets, the hot/cold mixing valve, the city-water inlet and fresh or grey water tanks also see hard use. A 12V water pump, tank or faucet is a straightforward DIY swap and one of the most common MDC replacements.
Electrical & solar
MDC leans heavily on Renogy lithium and solar systems. The solar charge controller is the component most worth understanding - if yours fails or you want more output, a quality MPPT charge controller or 12V electrical part restores (or upgrades) your off-grid power. Batteries, fuses and DC wiring round out this category.
Suspension, brakes & bearings
Corrugated dirt roads are brutal on running gear. Wheel bearings need periodic repacking and eventual replacement, and shocks, springs and brake components wear over time. Browse suspension and brake parts to keep the trailer tracking straight and stopping safely.
Awnings, steps & outdoor kitchen
The awning, stabilizer legs, entry steps and slide-out kitchen hardware all take abuse on setup and pack-down. These are high-use mechanical parts that benefit from replacement before they fail in the field.
How to know what fits your MDC
Because so many MDC components are universal or sourced from common suppliers, fitment is usually about the specification, not the brand badge - the thread size of a water inlet, the amperage of a charge controller, the GPM rating of a pump. Every product at RV Parts Giant lists whether it's genuine OEM or a universal/compatible fit, with a plain-English fitment note. If you're unsure, send us your model and year and we'll confirm the right part before you order.

Keep a small spares kit on board
The owners who never lose a trip to a breakdown are the ones who carry a few key spares: a backup water pump, spare fuses, a basic bearing kit and the consumables for their water and gas systems. A little preparation turns a trip-ending failure into a ten-minute roadside fix.
