I stumbled across this while surfing:
http://en.winston-battery.com/index.php/products/electric-vehicle
Interesting specs on the 10 seat electric bus (about the same size/weight as a GMC):
-20 minute quick charge or 3 hour charge
-280Km range with AC operating.
-cost per 100km: 39Kw/hr
-Nominal battery capacity 108kw/hr... Hmm so with your standard 30amp campsite power: 120V x 30A = 3.6kw so 108/3.6 = 30hrs + some extra for inefficiencies = ~36hrs to recharge at the campsite and that doesn't give you any power to run the AC etc while you are there!

Right.
Winston also owns the "Winston" all-electric motorhome that
MVP built here in Riverside last year. It was debuted in
China at one of the huge outdoor living shows to showcase to
the industry and scientists/engineers the capability of
Winston's batteries, and the possibilities of producing
all-electric RVs.
Since that time, improvements have been made in both the
battery package and controller system. Charge time is
somewhat reduced, and range is extended. The recharging
figures you quote are just about exactly what it took to
charge before its test run outside the plant. After that
run, it was recharged for loading at the port, and was towed
from Riverside to Long Beach. Folks were concerned that it
might not have enough juice to get it loaded as it had to
sit idling for quite some time before the hoisting sling was
attached. Even after the boat ride, it had enough to get off
the boat, out of the port and almost into the exhibition
hall after a quick run down the highway.
Vehicles of this type/size require real, grown-up, big boy
charging stations.
For a vehicle weighing 52,000 lbs. (including 16,000 lbs. of
batteries) it was/is quite sprightly and magnificent to behold.

Hi Toby
Are you checking out what the details of converting a GMC motorhome would be?
Also, the cost.

Darned impressive!
I'm wondering if there is an internal
combustion powered generator on board
for auxilliary charging.

Not specifically for the GMC, but MVP have shown the
all-electric Class C prototype at Louisville just this past
December. The motor/controller supplier has made/is making
the proper adapter plate(s) to mount the electric motor in
place of the gasoline engine. Although built on a Ford
cutaway, if a sufficient market existed for a GM adaptation
- especially a bolt-in for the transmission, such a
conversion would be possible.
No matter how sophisticated or affordable the motive device,
the limiting factor is and probably will be for the
foreseeable future, the battery pack required. That means
weight. My guess would be that a battery pack - even
Winston's, which are quite compact - sufficient to make a
practical conversion would weigh in the range of 3-5000 lbs.
Maybe not - I'll have to ask what the packs in the Class C
weigh. One could probably fit the batteries in the space of
the fuel tanks. But it would be a far cry from the 350 lbs.
or so of the gas. And I'm not sure the GMC has the
structural strength for that much dead weight. Without some
serious cambering of the frame rails, it'd be a belly
dragger for sure.
Batteries - it's always the batteries.

It is good to see advances in this area. (It would be nice if it was a US company, but we do not need to go there.)
Other than a few very limited uses, it still isn't practical.
I doubt that an electric RV, that would allow the travel that is normal for our rigs, will be available any time soon. But a "more limited" variation might be: It would be nice to drive 2 to 3 hundred miles, from one RV park to the next, and charge up over night for the next days trip. It would take some planing, but it could drastically reduce the cost of traveling the country... until the RV park operators caught on. 
I am not holding my breath.

HMMM Guessing 80kw average to make the GMC go down the road at 60 mph. 400kwh battery pack. Guessing average 10 lbs per kwh about 4,000 lbs of battery. get rid or 800 lb engine and add 100 lb electric motor and 100 lb controller and hardware. Take out 350 lbs of gas and 100 lbs of tank and plumbing. Also take out 200 lbs of radiator and coolant. Looks like a gain of about 3,000 lbs of weight. Just a quick guess anyway. Could probably get rid of the trans and final drive and put in a simple 2 speed box with a reverser so that would take out another 300 lbs or so. No torque converter so no need for a cooler. Might be doable but it would be a long term project. Have to think about that.
