By golly fellows, you just may have inadvertently stumbled upon a C3 refrigeration system! Now all you do is add a compressor and condenser.

Ever been to a tractor show and seen the big one-lungs running off a bbq tank.. and after sucking on it for a few minutes the thing freezes up.

remember the cooling effect of releasing a compressed gas....

I was wondering if you were thinking something like bbq tank. I have a 250 gallon propane tank. I guess there could be a problem. I am not sure how much of a draw it would take to do that. I have had my tank for over 15 years and I have had 100,000 btu of heat going plus the cookstove at the same time and did not have a problem I dont know the useage for a generator so I would have to look into that. I also see pickups and at one time school buses that used propane. The pickups just had the tank in the back of the truck and were powering a v-8 engine with that. Would a generator have a larger useage than a v-8 engine pulling a trailer ?

Usage will depend on power generated and efficiency.. however..If you got a large sump for evaporation.. and a large surface area.. I think you will be fine..

Never deviated. Thought fuel economy was brought into play as part of the issue or did you miss that?

You fellows always in the habit of ignoring facts if they don't suit your opinions

Didn't miss a thing. The issue was the fuel economy of a loaded vs. unloaded diesel engine at a set RPM, not the fuel economy of your loaded vs. unloaded pickup. Apples and oranges. Especially if you don't have any idea how much horspower your truck is actually producing in each situation (and judging by your "shouldn't the Fuel Mileage just go to astronomical levels if it's about HP required" comment, you don't).

Your truck requires about 60-70 hp to propel itself at highway speeds. Probably 100-110 hp-ish with your load (no wind). You get probably 18 mpg empty and around 11-12 mpg in your loaded configuration. A little quick calculator work, and it looks like you"ll use about 30-35% less fuel when you're using 30-35% less hp. How much more mpg are you expecting when you're unloaded? What facts am I ignoring?

I've had my 2001 Dodge Cummins on a dyno a couple of times, which told me what boost pressures roughly equate to various horsepower outputs. And I've towed/hauled many different configurations, including something similar to what you have in your picture. So that's where I get my facts. You?

Me, Nope no dynos. Heck, I don't even know what boost pressure means. I just go by what the load/mileage data shows.

I do like to equate things to the amount of sweat on Syphilous's headband though! Thats kinda like saying how much work was done ehh.

Sota depends on how much one pays for wall paper I guess!

I think he may be saying that the regulator should be sized to the flow rate of C3 required.

Now if it gets down to -40C or is it -40F then it may be time to take other measures.

if it gets down to -40c or even to -40F I will take other measures it is called pulling up stakes and moving farther south

That is the proper alternative although it was not available for some of us.

Course other's that have not had the benefit may try to talk about it!

I am not worried about doing that. If it gets down to -40 in arkansas you folks that live north of me will be frozen popsicles. I dont remember when the last time I saw it get to 0 degrees F
here.

No way!! It's the occasional -40F that keeps my area sparsely populated and keeps my land affordable. Plus, I'll go through a hundred Idaho winters vs. a single Arkansas summer.

I'm sure you'd say just the opposite, though. Different strokes for different folks.
