Why? 
I have a CNG station about 15 miles away and wish i could find a quality conversion kit and installer.
Im just ciriuos
What is ur mpg going to be after conversion ? Does it stay the same or in reases ?
How much is the price per gallon for lpg?

to save money on fuel costs per mile driven.
My understanding that the payback period is about 3 years for a mid-size car but even faster on a gas-guzzling SUV. I have read that the cost per mile can be reduced by 30% or more depending on your vehicle.
a gallon of LPG is about $3/gl.

A gallon of LPG in Lynden, WA is 2.19/Gal I figure that's a pretty good price. I saw an 04 Cruiser with setup to run LPG/Gas dual fuel - I was tempted to buy it. I think someone picked it up though.
I figure it's about a 30% cost savings overall for fuel based on my calculations.

Cool idea. Just remember that u need to fit the tank in the back, how big is the tank ?
Couldn't you relocate the spare tire to a swing out rear bumper and place the tank in the spare location?
Why?
Why not mitt? Or should I say mittens?
Save money, better for the environment, burns cleaner.
I know, I know, blasphemy!
I thought there might be some LPG conversions on 100's in Australia.
Might want to talk to the 'Got Propane' guys. They do a dual fuel HiLux (22R/RE I think) and may have some input or useful parts.
Dual fuel would be cool! (but the pioneers probably won't save much after the expense of the first installs are added up and compared to fuel costs)

What I'd be wondering about is the longevity of the engine, and overall wear... Is propane more/less wear? Does anyone know about the long term effects? This is important seeing that the 4.7 is easily a 300k+ mile engine.
I've studied this since I've been running a Detroit Diesel 6v92 Turbo engine on waste motor oil (WMO) for a couple of years. LPG is great because it is cheap and it keeps your engine squeaky clean. No soot, no carbon buildup...nothing. Clean your exhaust pipe tip once, and you'll never have to clean it again. But, you will not get equivalent MPG on LPG as you would on Gasoline. If you get 15 MPG on Gasoline, you'll likely only get around 9 MPG on LPG. Not quite as efficient. But this is an off-road forum, don't take my word for it, Google searches will reveal more info for you.
I think quoting a 60% drop in fuel economy is hitting it too hard. In reality, throughout all the research I've done, including interviewing the previous owner of that rig it seems that ON AVERAGE the drop is about 15% - so if we account for a rough 20% drop in actual economy it still accounts for a 30% drop in fuel costs per mile driven. Still a good deal in my books.
My math too...but I'm a dummy.
That being said, he's right, even a 40% drop is a little harsh...more like 20% which is what he said. So yeah, a 20% drop in MPG. I'm certainly not saying don't do it, just don't want anyone to do direct comparison...cost to change over is somewhere in the $2500-$4000 range give or take...add the 20% drop in MPG and then you have some real numbers. Truth is, your engine will thank you...the environment will thank you...you will have to find places to fill up at a decent price, and your insurance may be higher (I've chatted with guys that had a $30 a year increase which is nothing). You'll definitely want to get a yearly LPG service to keep things in tip top shape. If I lived in Cali or Arizona, I'd do this just so I could use the HOV lane. Seriously. But I drive all over the country and never live in one place more than 6-8 months so I never really get a chance to find local fillup stations. A guy online who converted his RR said off-the-line accel wasn't as sprightly as before, but again, tradeoffs. If you have Natural Gas at your house, you could do a NG conversion and install a pump at your house. http://www.cngnow.com/vehicles/refueling/Pages/refueling-at-home.aspx

I like the idea of dual fuel but the 40% might not be that far off.
My fuzzy logic goes like this: The folks who have done this have often done it with economy/environment in mind and so their throttle application may be a little more gentle than the average LC owner who likes to stomp the V8 and didn't buy the thing with hyper-mileing in mind.
Given the power reduction, the power hungry may spend a lot more time at WOT on CNG or LPG pushing the economy down.
As to why:
I have a buddy who's a bit of a 'prepper' and he wants an LPG conversion so he can go steal everybody's grilling fuel when SHTF and nobody has any gasoline. Not my style but to each his own, can't fault excess versatility in an LC.
