I just wanted to say thanks to everyone especially Mr. Quadzilla for all the information on propane I have been seeking over the last few months on this site and the last year elsewhere. It was a great help.
Now on to the fun part. Propane is awesome. My truck ran like a monkey on fire before, but now it is unreal. An objective opinion after playing for a few days is that it did little that I could notice from stoplight to stoplight. A lot of that had to do with the fact that I don't like giving my truck alot of hell while running through gears. Not on the other hand on the highway, it was unreal how much power the stuff hand over to you. Even with light accelerator application, its like you start taking off. On an assertet application, you literally have to back out to keep from getting into the high 90's or 100's. I am now a bonafied Propane Advocate. Set up and used correctly of course. The fun part is that I am still not finished fine tuning the Powershot system I am using. Its hard to believe it might unleash more power... Anyway, thanks again to everyone who I drew information from in the process.
i got the powershot2000 system. I researched for about a year beforehand, and it seemed the simplest, safest, and didn't require an engine coolant vaporizor....... I can't say that it is best system, but definately the safest and most user friendly....I like how the introduction of the gas is proportioned instead of "dumping" propane at a certain boost. Its really smooth. The only time you will feel a jolt of power is if you are above the preset boost level with the system off, and then turn it on, then it kicks in gear pretty hard.. Otherwise it is a powerful yet smooth difference. Now that i'm pretty close to finished with all my toys on the truck, I am starting to create my gallery, I will post pictures of my beast very soon......

I couldn't tell you, I've only filled up once since i installed the kit, and the way i've been driving wouldn't indicate a positive result. I'm going to make a 500mi trip next weekend where I plan to use it moderately on the highway, and I'll let you know.
If you set the propane to come on moderately on the freeway, you'd reach maximum mpg improvement. If you "wick it up" and have the propane come on quicker/stronger, you'll see a larger improvement in fuel consumption, but will use a lot more propane in the process, which offsets the gain in diesel usage. When the system is set properly, many guys report a 2-3mpg improvement.
Doesn't seem to me that 2-3 MPG would cover the cost of propane neverless the kit cost. But it sure does sound like fun.
I agree. If you're thinking of adding propane merely to save fuel, you'd have to drive for a long time to recoup the savings, since the propane fuel itself is an additional expense. I did it for the power increase, and the improvement in the overall driveability of the truck.
If that's your rationale, you won't be dissappointed.
