Anyone driven a truck with one of these?
How does the battery hold up for heating and cooling?
If the system was added to a truck that had a driving history, how was the fuel economy impacted?
This system has attracted my attention. I am at least a year or two from a new truck, but I am strongly considering one of these in a truck with a X15 efficiency engine.

If your fuel cost is about .40 per mile and you increase fuel efficiency by 10% your fuel cost is now .363. At 15% if goes to .347.
Let's say you save .04 on the average per mile, in a perfect world. If the system costs $10,000, your break even point will be at 250,000 miles.

I don't like the idea of increasing my tare weight by 800 pounds... maybe it's different if you're always light weight. If you're light weight and seeing .40 per mile for fuel already then the savings are still not that impressive over the life of the truck.

Fuel savings there would compound on the driving fuel economy.
It is something new. I am not getting starry-eyed over it, but I do hope to find people who have driven a truck with one.gokiddogo Thanks this. -
I've only heard mixed reviews on those battery apu setups. If it provides cooling for 10 hours how does it provide some extra torque when you fire up in the morning? All you're really doing is converting energy from diesel into electric via alternator then using the electric to turn the wheels. Law of conservation of energy says this will only result in a loss. I am skeptical of their mileage improvement claims. I suppose one could claim most of the time the alternator is turning anyway and doing nothing most of the time. So may as well charge batteries. I would say put the alternator on a clutch so it doesn't draw any horsepower. The difference will be very small either way.

800 pounds of weight to recapture the energy used to move the 800 pounds in the first place.
That's a head scratcher for me... -

For a real comparison you will need 2 identical trucks doing the same work, one with the system the other without...
Or, better, someone who does a dedicated run and installed the unit, for before and after real world results. -
Snailexpress Thanks this.

Fair enough.
Does the website say the cost of the system or do you know that number?
