A Ford salesman reported the dual 250-Amp alternator option on 2020 Transit will have a MSRP of $495. That’s a small fraction of cost compared to aftermarket 2nd alternator kits used on most generatorless motorhomes built thus far.
As discussed in other threads, this new OEM equipment can bring an inexpensive generatorless motorhome option closer to high-volume reality. By adding larger battery bank and larger inverter/charger, it will be much easier for RV manufacturers to build a “light” version of the Volta system at a much lower price. Cost of the 2nd alternator was greatest unknown. We still don’t know what Ford may charge for this option on E-Series with 7.3L V8, but it should be in similar range.
Most important to me is that by being OEM (Ford), there shouldn't be warranty issues and the installation should be built to a higher standard of refinement and reliability.
Let’s hope RV manufacturers capitalize on this OEM dual-alternator option and start offering a system with price similar to an Onan gasoline generator. It can be marketed as an option so buyers can make final decision.
