Thor's Jayco and Entegra divisions have released new propane-free lithium battery models of their Promaster based Ethos and Swift vans for 2022. Both models use Elwell's Timberline gasoline-fired combination hydronic heating and hot water system. To the best of my knowledge this represents the first widespread deployment of the gasoline-fired Timberline system.
Elwell's diesel-fired Timberline system found quick success in the higher end Class B market, having replaced Winnebago's original Espar/Rixen system in 2020 and later Revel 4wd vans. Since then it's also become standard on Airstream 24X, Jayco Terrain, Entegra Launch, and Tiffen Cahaba sprinter 4wd Class B's.
Winnebago switched their Travato 59GL and 59KL models to induction cooktops for 2022 but continued to use propane for furnace and water heating. It will be interesting to see if they also switch to Timberline's gasoline heater to eliminate propane in upcoming releases.
