Also it is a step till the hydrogen PEMs replace the ICE and generator.
an old saying if you have to ask the cost, you can't afford it.
However what is the cost to the environment
If ICEs were used only where they make the most sense, such as recreation and travel to remote areas, the impact to the environment would be minimal, AND fuel prices would bottom out to about $2/gallon. The major environmental nightmare is due to unreasonable long commutes by individuals in overpowered inefficient vehicles which spend most of their time in stop-and-go traffic or speeding 90 MPH trying to make up for lost time, or just venting frustration. RVs probably contribute no more than 2% of the total CO2 and noxious gases that harm the environment, and they very likely consume a similar low percentage of all fossil fuels.
Also, RVs are large enough that they can make use of modern diesel hybrid technology, which may be able to achieve 50-60% overall efficiency compared to 20-30% for standard ICEs, and they may be able to incorporate scrubbers and other technology to reduce emissions. Because of their low overall percentage of fuel use, and because they are often driven and parked in rural areas near farms, they are prime candidates for biofuels.
Unless there is a tenfold improvement on battery technology, I think all-electric RVs are beyond what is practical, affordable, and acceptable for most RVers. I would put more effort into solving the overall wasteful and inefficient and unnecessary energy consumption by the 90+% of people who take it for granted that they should live in a McMansion many miles out in the country or suburbia and make a 100 mile or more commute every day into cities to work at jobs that allow them to live such lavish materialistic lifestyles, yet have so little time to enjoy the natural surroundings and instead isolate themselves in their large climate-controlled rooms totally absorbed in video games, internet social media, and high tech entertainment.
