ALL ELECTRIC GMC MOTORHOME

That’s impressive. Batteries will improve over time.

What would be nice is adding a 5-6 speed transaxle that could help in reducing draw of the batteries. Well for that matter the current engine too.

The current motor could use a 6-speed transmission a lot more than the
eclectic motor. Eclectic motors have a very wide power band. Tesla cars are
one speed going from stopped to over 100 in one gear. For the
eclectic maybe a 2 speed with a 20 to 1 difference could be utilized.

Finding an easily adaptable transmission for our GMCs seem to be a #1 priority. The way things go, availability of TH425 may become a limiting factor
for longevity of our coaches. There are plenty Olds 455 and 403, plus a variety of other custom builds and new engine swaps that may work. The good
old TH425 is the only one that fits into the engine compartment without extreme engineering challenges and fabrication.

I completely agree - technology will get there eventually. The initial ramp up from idea to prototype, to something that is everywhere just takes
work, persistence and time. Every other technology had gone through the same process. Anyone here remembers the time when computers used to take up
the entire rooms? The only people who could operate those computers were specialists with education and multitude of qualifications. These days,
more computing power is sitting in your back pocket in a form of a little black rectangle and your grand kids can run the flight simulator on their
tablets.

My thinking is a hybrid would be best for a motorhome with todays technology.

Get rid of the generator and propane and use all electric.

A gas, or diesel, engine with enough power to move the rv at highway speeds and charge the batteries and run a heat pump.

Probably 20 years ago or so, San Francisco municipal transit tried out some
special busses that were powered by a unique power plant that used a form
of energy transfer that constantly recycled from a liquid to steam and back
to liquid.again. if I recall correctly Bill Lear, of Learjet fame, created
the power package, and mothered the program. I believe that his health
failed about the same time. He had a unique name for the power package that
escapes me today. The transit drivers commented that the system worked very
well on those steep hills. If I remember correctly, they were fueled by
hydrogen. But, they did not have to plug them in.

Ah — the Lear Vapordyne. He tried to enter a car based on this power plant in the Indy 500. Recirculating steam turbine (waterless). Would be great for electricity generation. I have had thoughts of a power plant like this for the last 25 years. The components are all commercially available now for someone to put them together into a power plant of that nature. Someone with free time and spare money should give it a shot!

If you are concerned about ultimately replacing the 425, you might want to check the specs on the HUMMER Electric transmission. It is 4wd so would
have a front drive as well as the rear. I have only seen the TV ads and haven't dug into the specs. With today's demand for ride comfort, I would
suspect it is independent suspension yet heavy duty.

Yea bring back steam power.
Use coal to boil the water what a step forward.

Obviously you have never been to a Steam-Up, or been around a nuclear power
plant, or around a modern ocean going ship. Live steam only releases water
vapor into the environment. Pollution free in the case of power plants.
Turbines are quiet and efficient. They have their place. I love to see a
steam traction engine from the late 1800's hooked up drawbar to drawbar
with a modern diesel tractor. No contest at all. FULL PULL!!! Every time.
Those steam engines are pretty impressive. Lots of them burn waste wood,
not coal or petroleum products.

OK waste wood.
So we need to pull a trailer of wood .

Well Jim,

Now you are in my territory.

I have seen one of the contests you suggest. I have forgotten who built the traction engine, but the opponent was a Case 2670 (new at the time). The
traction engine had a weight advantage and steel cleats. He let the Case pull him backwards a little ways before the operator opened his throttle.
First, he just held ground, then linked in a little more and dragged the rubber tired Case backward with the tires tearing up the dirt. Some
complained that the antique had an advantage on dirt. So they moved to some McAdam. This time, the tires smoked as the steel cleats tore up the
pavement for the same outcome.

Steamships are not all that clean. We normally ran with a little haze from the stack, and then again, we were burning heavy oil (aka residual fuel)
at the rate of a barrel (42g) per mile. As ton-miles per gallon, that is actually pretty good.

Did you know that the Pennsylvania Railroad built and ran a direct (well, gear) drive steam turbine locomotive for a while. My father pointed it out
to me, but I was like 5 and while a railroad fan, was not capable of understanding what I was looking at except that it was clearly strange.

But, on the subject of all electric motorhomes...
Thetford engineering had a program in 1973. It was a Travco that had a big block for power and 10ea (yes, count-um 10) grp 31 batteries to make a 120
house bank and a huge inverter charge that was a special build. They tried, but they still needed to have an onboard APU. The guy running the
program had lots of good ideas, but I had my own program and could not pay that much attention.

The Greater Midwest Classics had a informal rally at the "Threashermans Festival" in Andover SD this past September. We witnessed the Steam driven
Case 150 Road Locomotive hook on and pull a world record 36 bottom plow across a field without even sweating. He finally had to lift when the rain
made the field so greasy that loss of traction had him slowed to a crawl. This Case 150 was hand built by the owner from original drawings obtained
and later digitize from JI Case. Next year he will pull a 44 bottom plow and two yrs from now on the Threshermans Festival 50th anniversary, intends
to pull another world record of a 50 bottom plow. Here is a video of the tractor pulling a 24 bottom. What an animal!

Can we please forget about steam power.
Yes steam has a lot of low speed torque but so does electric propulsion.

As far as the need for a APU why do we need it when a hybrid already has a engine to make electrical power?

Just so you have a point of reference, in 1906, a fellow named Marriott,
drove a Stanley Steamer automobile to 129.6 mph. That ain't slow on
anyone's clock. Just Saying.

Just because you can pull 24/40/50 plow bottoms with one tractor (land locomotive...) doesn't mean you can use them for any practical purpose. Why do
you think there aren't any of them left around on the farms? How much does that behemoth weigh? Now figure out how much compaction (weight per
square inch) is created by having only a small foot print of 4 wheels. You can turn all the soil you want after that tractor, but you'll never break
the compaction layer. It will be there below the plow pan. Over time, you compact soil enough that the roots quite literally can't penetrate the
soil layer and you can kiss your yields good bye. Lot's of research done there and that is part of the reason farmers are going away from plows too...
Couple examples of soil compaction in agriculture -

Steam might be fun to play with, but burning stuff is still burning stuff. I'd rather charge make angry pixies (charge batteries) from the sun/wind
and run electric, rather then burn straw/wood/cow dung to make steam.

Uh, probably not. Just hit the enter key if it bothers you.
