No major technology improvements except on the gas chassis as was already mentioned. There are 3 stage converters on models that don't have inverter/chargers. The RV customer generally doesn't like change so I doubt there will be much, if any, major changes to RV's. I'd personally like to see the elimination of 12V in rigs (at least in the house portion). Have the rig run solely from 120V straight from shore power or through an inverter if camping off grid. Since it seems the majority of RVers use FHU CG's this shouldn't be an issue and for us off grid campers, offer additional batteries and more charging capability (with solar and/or higher amp chargers). Call it a boondocking package.
