Newmar was founded in 1968 in Nappanee, Indiana, and became part of Winnebago Industries in 2019. Newmar builds Class A motorhomes, from gas models like the Bay Star and Canyon Star to diesel pushers like the Ventana, Dutch Star, Mountain Aire, London Aire, Essex, New Aire and the King Aire flagship.

Battery setups
Newmar diesel coaches generally have multiple chassis batteries and a sizable house bank, often with a large inverter-charger running much of the coach. Some recent models offer lithium house batteries from the factory.
What we see in Florida
Large AGM or flooded banks near the end of life. Replacing a big house bank all at once is a real expense. Testing each battery first tells you whether it is time.
Inverters left on in storage. A big inverter draws power even with nothing plugged in.
Factory lithium systems. These need to be replaced or serviced with the coach's charging and monitoring design in mind.
Upgrades
Many Newmar owners move to lithium for usable capacity and weight. On coaches this size, the job often involves inverter-charger settings, alternator charging and battery monitoring.
Fitment note: Battery locations, tray sizes and electrical packages vary by model, floor plan and model year. Treat this as a general guide, not a fitment guarantee. We confirm what your RV has before anything is installed.
