OPUS Camper Parts & Accessories (US)

OPUS campers are a common sight on US trails, but tracking down parts and accessories often means a dealer form or a wait. RV Parts Giant stocks compatible components for OPUS owners and ships them from the US — so consumables, upgrades and replacements are a click away.

Built for the OPUS range

From the air-inflated OP15 and OP Lite to the OP4 and OP2, OPUS campers share many universal systems — 12V power, water plumbing, solar and awnings. We carry compatible parts across all of these, plus the everyday consumables that wear out first.

What you'll find here

  • Solar charge controllers, batteries and 12V power components
  • Water pumps, tanks, faucets and city-water inlets
  • Awning hardware, stabilizer legs and jacks
  • Suspension, bearings and recovery gear
  • Outdoor kitchen, sanitation and interior fittings

Honest fitment, every time

Each product is labeled genuine OEM or universal/compatible, with a plain-English fitment note. If you'd rather check first, send your OPUS model and we'll confirm the right part before you order.
