I like eliminating the propane and using induction cooking.

You could fit up to 8 400 watt solar panels on a 26 ft. coach.

The weight problem of adding a 100kv range extender, generator, and its
fuel along with a 75kwh battery pack would need to be solved.

You could charge at camp sights with a 240 volt 50 amp service.

You would probably drive 75 to 100 miles before the range extender was
needed. If you knew you would need the extender, it could be started after
about 25 miles.
This would be the equivalent of the BMW I3 on steroids with solar panels.

Mghamms,

Why do you want to stick with all that iron/plastic age stuff?
As long as you are doing all that, make some worthwhile changes....
Make the whole thing a monocoque vacuum molded of epoxy and carbon fibre and assembled with frame of similar structure.
Why stick with 6 wheels? Make it 8 and all with regenerative braking and active anti-lock.
You can either make them all torsion bar or give up a little interior room and make them all struts. My 95 Honda has rear struts and the truck is still good.
You could controllable damping struts like my 87 T'coupe and and for a little more, you can make them do you active leveling.
Because you will want the whole front for the battery bank, put the diesel in the back under the queen walk around. Either a Hall-Scott or Cummins buss engine (the lying on the side version could fit under there just fine. You can leave the fuel and black tanks where they are....
Sounds like a good plan to me.

Matt

I think your correct hertfordnc, ground zero of this tech development would be with large truck fleet delivery. Any sources of articles for that development out there?
Jim K, any comments or info pertaining to upcoming battery development?
Hybrid to me looks more viable from the security of having multiple options for propulsion considering the vast terrain and locations we take the GMC’s. Pure electric range could be affected by just climbing steep grades in mountain range so I’m wondering if a hybrid setup is possibly a better arrangement. Taking the worse case scenario such as mountain range driving and meeting the needs of that would be to me the starting point if this was even possible for a RV. Steep long grade climbs along with potential infrequent refueling locations would be to me the benchmark. I would like to know more of how a series hybrid works off a generator. Having all wheel hubs with a electric recharge ability sure sounds like the way to recover energy in mountain driving but it would certainly come down to the numbers. Anybody good friends with a GM exec? Kinda wonder if Matt has a good point where you would have to lift our GMC onto a lighter composite frame that already has these drive train systems installed?

I grew up during WW II and our milk was delivered
in 1 qt glass bottles using horse drawn carts. The
homogenizing process apparently had not been
invented and the cream would rise to the top of the
bottles. Everybody (?) had a siphoning device to
get the cream out of the top to put in their coffee.

In the winter (northern NY state) the product would
freeze on the back porch and push the paper cap up
out of the bottle a little bit.

Speaking of electric delivery vehicles, nothing new there, really.

I grew up in the UK when milk was delivered door-to door every day. The entire country had massive fleets of 3-wheel electric "milk floats" delivering
crates of milk in glass bottles. Apparently there are still some updated ones in use today.
