Since your Gov't will about pay for the conversion, and the cost of LPG is 1/3rd the price of petrol, it sounds like a good deal. The only "fly" is that the tank will take up some valuable space in the vehicle unless they replace the gas tank w/ two smaller tanks side-by side.
Expect a 20-25% decrease in fuel mileage based on volume of fuel (liters).
I get about 22-24mpg (US gallon = 3.785 liters I think), which is 6.35 miles/liter. You may use km/100liters, so that's 1016km/100liters with my 2000 TJ w/ the 4.0liter 6cyl and 5 speed (3.78 dif and 235/75-15 tires). A lot of it is driving style, and I know folks that get only 14mpg (600km/100liters) if I did my math correctly.
In any case, if you get the conversion almost free, with that price of fuel differential you cannot lose. A bonus might be resale as well, assuming the conversion is a sought after one.
Here in the States, LPG is VERY unpopular, and in some places VERY expensive. It's ALWAYS a pain to find and buy it. At most stations you can fuel with petrol immediately, but an LPG stop may take 30 minutes!!

P.S. I lived in Alaska, so when I said "cold," I mean COLD. Even at 20 deg F (-7 deg C) it becomes reluctant to vaporize, and at -40 F (also -40C) forget it!

Hmmm, interesting points you raise there Bob. Well we live in Australia and here, our fuel is almost $1.50AUD per litre and LPG is 49cents per litre. The government is offering $2000 to anyone who converts to LPG. It's just that my son has the Wrangler and I love the thing but it's so damned thirsty!! My husband and I drive a Suzuki Sierra, I think you call them Samurais over there and it's a fantastic little car...done 280 000km and never had work other than a clutch plate change done on it, goes absolutely anywhere and is cheap to run. Would love to cut costs for my son. I don't think cold weather would be a prob here...we are in winter right now and our temps range from 10C to 25C.
