EV alternative for light/medium duty trucks

I am the OP. I just read through the entire thread again. You still haven't convinced me that you can replace all vehicles with electric or hydrogen, then rebuild the entire infrastructure system converting natural gas to hydrogen or building the new electric transmission lines for less money than onsite production of hydrocarbons as a refinery feedstock at renewable energy facilities.

I think with both hydrogen and EV's, the cost of fleet replacement and building the support infrastructure are vastly under estimated. My way, you pay as you go. It is invisible to the consumer.

Nobody will be able to because it is not possible with the current technology at this time in the current technology development path. EVs are great for commuting and city traffic, but they fail with heavy load and long trips (which makes them quite difficult to use towing a trailer or fifth wheel).
Hydrogen is a great technology, but the only cost effective technology is direct sea water extraction and there is no solution for distribution in place yet, so we are looking between 10 to 20 years at best.
To your original question, from a person familiar with EVs and Hydrogen technology (and a long time owner of both), neither technology can replace ICEs today for the RVs application in most cases.
Now, if you have a very light trailer and are willing to put up with the charging, there are really good EVs that could work (some postings have actually shown). Besides that, Not currently available on my point of view.
(And as I normally say, my point of view is my pocket and my convenience; I will use any technology that is cheaper to own and as convenient for me than the alternatives)
