Any discussions about converting a GMC motorhome to an electric drive?
Possibly pulling out the 455 motor and the transmission and replacing them
with an electric motor, tons of batteries on the bottom of the coach and
solor panels on the roof.

Has been discussed in the past, Cost/benefit ratio is way below zero. You cannot put enough batteries on the chassis to get it down the road very far. Weight is the killer and solar cells would be no where close to the amount to provide adequate recharge capabilities.

Yes, not worth the money. Some guy posted pictures of his Telsa Model X
towing a 17ft travel trailer. It's range went from 250 miles to 100
miles. He said the model x was $150k.

Best bet would be a hybrid.

Keep the V8, add in-wheel engines for the back wheels. Put batteries in
place of one of the gas tanks.

Will give you much better mileage in the city, and way better traction
on grass

I want to rip the system out of one of these when they come out and put it into a GMC :)

I bet you that would work as far as range and battery capacity concerned. Cost... I'm sure its going to be a lot.

that price is for the whole semi

If you buy the semi, might as well use it!

To build your own I'd get motors, batteries and controller and retrofit it into the GMC

Put the batteries under the floor, theres a ton of space there especially without the gas tanks and the exhaust

Probably for $50,000 or so you'd have the parts ha ha ha ha

Just make the GMC into a 5th wheel, and Bob's your Uncle. No tornado front
hubs to worry about, and regenerative braking, too.

I spoke to a Prorean engineer a year or two ago, he claims it would be possible to drive the rear wheels with a torque sensing controller to
supplement the 455, since then, I'm involved with an electric bus project with proterra, a 440kwh battery, they just broke a record driving a 40 foot
bus over 1100 miles on a single
charge...https://www.proterra.com/press-release/proterra-catalyst-e2-max-sets-world-record-and-drives-1101-2-miles-on-a-single-charge/

Many transit agencies are flicking to this technology, the trickle down effect should be commercially feasible in next several years...

I haven't seen any discussions so I'll to start one. I watched a recent Jay Leno's Garage episode and Arnold Schwarzenegger was showing off his SUV
which had been converted to all electric by a company in Austria - I don't know if Arnold has any ownership of the company but I'd bet that he has
some interest. Arnold has now sent his Hummer there to have it fully converted too. These are not hybrids, they are 100% electric. I looked at the
company's web site and they have converted many vehicles including a small truck rated at 3.5 tons. I wrote to them and asked them how many GMC
motorhome conversions would get them interested and at what price. They blew me off and said they are looking for manufacturers as customer and would
not talk about small batches and didn't comment on the suitability of their product for the GMC. Also, Arnold's Mercedes G-Wagen is now worth $1M
according to Jay's video - I doubt if the electric conversion cost that much but figured if it could be had for $30-40K there might be some interest.
The company is Kreisel (kreiselelectric.com).

That is exactly what I was thinking. Use their motors (rated for heavy duty truck) and the control system. Batteries under the floor in place of the
fuel tanks. If one was to keep a small fuel tank for Onan, you got yourself an extended range "hybrid" :)

If you are going to go to all that trouble, why not just put an electric drive on the Onan? ;)

Not following you on this one. Drive Onan generator with the electric drive? Then we can plug it back onto itself and get the generator that will
charge itself while running :) Perpetual motion machine?
Anyhow, this is just dreaming. If I had crazy millionaire money then it would be more than just dreaming. I'm just glad that the technology is being
developed on multiple fronts out there. I'm super happy that there is a network of support for rebuilding the old engines and the transmission on
these coaches. However, without new units being manufactured, we all know that the day may come when you may not be able to get a replacement for the
one that just broke. Hopefully long before that, there will be other more or less affordable options to upgrade/change the drive system.

-EV West creates custom Electric upfittings. Their building a Pinzgauer
which will be interesting! XL Hybrids is an upfitter for Ford who EV
enables our commercial vehicles. Its all possible, but I agree that the
hybrid is more attractive than pure EV for RV purposes.

Prius battery packs are showing up in Men's Malls. Price seems to be around $600 - $800. It's a start.

So just looking at the Proterra specs for their smallest unit - 35ft. It can go 55-72miles on 94-126Kwh of energy.

So we'll say that's 63 miles on 110kwh of energy, so that's about an hour's driving. So you would need a generator capable of at least 110kw
continuous to keep up with the energy demand if you like hybrid. That's equivalent to 20 Onan's putting out near full rated power.

One HP = 746 watts, so 110kw/ 746 watts = 147hp is the electrical equivalent steady for an hour for their electrical consumption.

A 100AmpHr 12V battery = 1.2kw so you would need about 100 batteries to drive an hour at this rate, but actually more. Lead acid should not be taken
below 50% charge and li-ion below 80%. so even Li-Ion will need about 125 batteries. At about 40lbs each that's 2.5 tons to add. 100Amphr batteries
are going for ~$750 each so that's about $94,000 in batteries, plus chargers and battery monitor systems.

My sister recently bought a VW Golf EV. She took a pic of her power consumption to send me. It was 27.2Kwh/100km, so thats 27.2kwh for 63 miles or
about 1/4 of what this bus does. Her diesel VW likely got her 45mpg vs a bus at likely 5-6mpg, so I don't think she is doing very good with it.

EV get better city than hyway because they regenerate to charge the batteries while braking with little wind resistance. We do mostly highway with
little braking and high wind resistance, so its mostly just a continuous load.

I'd say their record miles on a charge was likely at slow speed, no more than 25 mph where the wind resistance is still low and only against rolling
resistance.

Just my farmboy mechanic, 45yrs in electronic technology way of seeing it.

My Staff says I never listen to them, or something like that
 
We had a Europian manufacture of motors visit us to see if we could install
them on each wheel.
We realized that were limited to the diameter of the rear wheels so they
went back without going futher.
Eventually they will come up with a more compact unit that can be adapted
and we might have a coach that can run on battery , Like Jim H says, the
amount of batteries will be challenging should one want to try..
