The Sprinter RV Upgrade Program targets both conquest buyers and existing brand loyalists. Customers purchasing new 2026 or 2027 model-year STRADA-ion, TURISMO-ion, or TERRENO-ion units are eligible for a $10,000 discount, while those opting for the VACANZA-ion model receive a $5,000 rebate. This incentive is applied directly at the time of purchase, removing the need for mail-in forms or delayed processing.

Participation is open to owners or lessees of competitive Mercedes-Benz Sprinter-based motorhomes from brands such as Airstream, Winnebago, Thor Motor Coach, and Roadtrek. Current Grech RV owners are also eligible for the rebate when upgrading to their next vehicle. Verification is handled through the vehicle identification number (VIN) at authorized dealerships, and crucially, no trade-in is required to qualify. A.J. Thurber, Vice President of Grech RV, noted that the program aims to provide immediate value for those seeking to transition into the company's specific brand of craftsmanship and lithium-ion power engineering. The offer is non-transferable and cannot be combined with other promotional incentives.
