OPUS campers are everywhere on US trails - and for good reason. The air-inflated tent design on models like the OP15 and OP Lite sets up in minutes, tows light, and opens into a surprisingly roomy living space. But like any imported off-road camper, sourcing parts and accessories in the US can mean a dealer form and a wait. This guide covers what OPUS owners most often need, what fits, and how to get it shipped fast.
OPUS models this guide covers
The most common OPUS campers in the US are the OP15, OP4, OP2 and the lighter OP Lite. While each has its own layout, they share the same core systems - 12V power, a fresh-water plumbing circuit, solar charging and an awning - and those systems use largely universal components. That's good news: many replacement parts are readily available in the US without going through the manufacturer.
The OPUS parts owners need most
The air tent and canvas
The inflatable Air Pole system is OPUS's signature feature and its most brand-specific component. Canvas, zips and the air poles themselves are best sourced through OPUS for an exact match - but everything attached to the trailer underneath is far more universal.
12V power and solar
OPUS campers rely on a 12V battery, solar charging and a charge controller to stay off-grid. The controller is the part most worth understanding: if it fails or you want more solar output, a quality MPPT solar charge controller or 12V electrical part gets you back up and running - or upgrades your capability.
Water system
The 12V water pump is a consumable - expect to replace it eventually. Faucets, the city-water inlet and tank fittings also wear. A replacement water pump, faucet or inlet is an easy DIY job and one of the most common OPUS fixes.
Awning, steps and outdoor living
The awning hardware, stabilizer legs and entry steps take repeated stress on setup and pack-down. Replacing worn mechanical parts before they fail keeps setup quick and frustration-free.
How to know what fits your OPUS
For everything outside the canvas and air-pole system, fitment is about specification rather than the OPUS badge - the GPM of a pump, the amperage of a controller, the thread of a water inlet. Every product at RV Parts Giant is labelled genuine OEM or universal/compatible with a plain-English fitment note. Unsure? Send us your OPUS model and we'll confirm the right part first.
