Chassis Context
The 2023 Winnebago Solis is built on the RAM ProMaster chassis — front-wheel drive, transverse 3.6L Pentastar V6 gasoline engine, and the 9-speed ZF automatic. Unlike Sprinter-based RVs, there's no DEF/DPF/SCR system to worry about, but the 2023 production year falls within the window affected by the ProMaster 9-speed parking pawl recall — verify NHTSA recall status by VIN. The ProMaster is also the only chassis in the lineup without available adaptive cruise control, which matters for long highway days.
What's Specific to the 2023 Winnebago Solis
The 2023 ProMaster uses the 9-speed ZF automatic (part of the FCA 948TE family) behind the 3.6L Pentastar V6. A specific parking-pawl recall affects multiple 9-speed production years — a VIN-specific recall lookup at nhtsa.gov is mandatory before any purchase. The 9-speed is generally smoother than the 62TE it replaced but has its own well-documented software-update history.

Any shop fluent in Chrysler minivans can service either; that ubiquity is a genuine ownership advantage.
