Hello BB,
OK, for heaters try
http://www.plantdrive.com/products/hotfox/hotfox.html, or
http://vegoilconversions.netfirms.com/ I prefer water heaters instead of the electric ones.
Where I logged on the Pacific Coast, it never got so cold we had to start a fire under a skidder or loader. But, one of the old-timers I knew told me he used to do that in Alaska. He taught me the trick of wetting a red rag with a little chainsaw gas, and putting it up to the air intake of a tired old IH cat (HD27?) we used for road building, and it always started right up that way. We never used ether. Well, almost never!
For tanks that fit along the sides of the front of standard long wide bed Fords, Chevs, and Dodges, try
http://www.nwmp.com/ . The tank you want is a universal 16 gal vegoil tank kit. It is not even shown in their literature. Both the 96 and 93 Chevs have two each of these. About 65 gallons total, and 1,000 miles or so between fill ups.
The 05 GMC crew cab has a Northern Tool (
http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200318087_200318087) 90 gal aluminum tank mounted cross-bed, and it is a short bed, so It loses 16" of its 76" long bed space. However, the benefit is, it goes around 2,000 miles between fillups!
I prefer to chemically treat first, and dilute 2nd, and heat as a last resort. BUT, if I lived in a cold climate, would have to change that order!!
In the winter, I ALWAY add PS Diesel 911, Diesel Kleen, and Biogel with every re-fuel.
You have my sympathy on the firewood. Cut it, hauled it, stacked it, and heated with it for almost 20 years...
The 275 gallon oil tanks from houses for heating oil can be found for little or nothing. Mount one in a heated place, and use that to feed the Listeroid. Look on Craig's List., the Nickel Ads, etc.
