I have a 2003 Silverado 2500 HD 6.0 L Extended cab 4x4 getting about 13 mpg combined C/H, when I tow my 22' TT or my 8' ATV trailer I get about 10-11 mpg. I've made two mods cold air system and after market muffler. Millage didn't change much.
Was thinking about doing an LPG conversion, not so much for an increased mpg, mostly cost. Here in the SW LPG cost didn't change as drastically as gasoline. My understanding is the HP and torque is about the same if not a little better. Would like to hear the PRO/CONs on this.

LPG burns very "clean", but from what I remember it gets a little less power than gas. The conversion itself is my questioin. Ford offers a LPG version of the F150, but the conversion cost around $10,000 extra. It can't be that expensive to make the necessary addd ons, but I don't know how much it does cost. Good luck and keep us informed, if you go ahead and make the conversion, please.

In Europe this conversion is very popular for "The Green Way" but it remains an alternative fuel, especially for the big greedy engines.
Here the fuel is very expensive and this solution is the most less bad.
The cost of conversion in France, for a TB I6 4.2L, is 3000€ ($4200)
In the purchase, these big vehicules can negotiate much more easily than the European cars
Fiscal advantages during the purchase of the vehicle and in some regions free car registration document.
For more details, see my mods:
Also, for conversion:
For information, in France:
Gasoline-> Inline 4, 1.6L (110HP)
Diesel-> Inline 4, 1.9L (Direct Injection 115HP)
The Diesel vehicules represents 75 % of the motor vehicle car fleet
Prices of fuels /L (August 2009):
-Gasoline Unleaded: SP95->1.22€ ($1.70) SP98-> 1.26€ ($1.76)
-BioEthanol: E85->0.77€ ($1.08)
-Diesel: GO->0.98€ ($1.37)
-LPG: GPL->0.57€ ($0.80)

Had a buddy with a propane pinto (worried about the exploding gas tank thingy) He would grin from ear to ear when the CARB guys would stick the sniffer in his tail pipe and get a puzzled look on their faces!
I guess today your conversion has to be approved. Here is a list of approved mfg/systems. CARB
Here is the address for OHG: OHG,. Inc. 10065A Greenleaf Ave. Santa Fe Springs, CA. 90670
Sadly it looks like they are out of business. You would think that in the interest of clean air, CARB would give you a break.There is no way to happiness....happiness is the way.:yipi:
