Chassis Context
The 2026 Winnebago EKKO sits on the Ford Transit AWD chassis with the 3.5L EcoBoost gasoline V6. No DEF, no DPF, no glow plugs — emissions maintenance is dramatically simpler than Sprinter. Early Transit-based EKKOs (2022–2023) had first-year fit-and-finish issues; by later 2026 builds Winnebago had stabilized production. Water heater plumbing on the Transit is routed closer to the floor than on Sprinter-based RVs, so sub-freezing protection requires running the furnace rather than relying solely on the diesel heater.
