Big Upgrades ($500+)

Big RV upgrades priced at $500 and up include major systems like a 400Ah lithium battery, a Victron Expedition Power Kit, Victron Quattro and MultiPlus inverter/chargers, and a Victron SmartSolar MPPT RS 450 solar controller, alongside structural additions such as a Pop Top fiberglass top for the HQ12, diamond plate panels, a spare tire carrier for the HQ15, and a complete external kitchen or full dinette set. Most items here are built for Black Series HQ trailers and the Dominator.

These are larger installs, so check the model-specific fitment notes and any tools or professional install requirements on the product page before ordering rather than assuming a drop-in fit. Orders ship from Upland, California, and eligible orders within the contiguous US qualify for free standard shipping, with free 30-day returns on a prepaid label.
