Convert Generator to run on propane

Update:  After more research I found some favorable reviews on the Forest River site for the "motor snorkel" from US Carburetion.  This fits between the carburetor and the air cleaner and moves the air cleaner out a little...maybe a quarter inch or so.  The other brands have an insert that moves the air cleaner out 1.75 inches or so.  It looks like there isn't room for the other brands to fit inside my Champion generator case.....so motor snorkel it is.  The generator will not have quite the output on gas...loses 10% on propane and perhaps 20% on natural gas according to most people.  According to the motor snorkel folks there is zero loss...but that's what they say.  

Natural gas is still cheaper than gasoline on a dollar per watt basis.  Propane is also cheaper...excepting with the current $1.85 gas price that probably isn't true any more. 

Kit is about $180 for the unit and regulator on the generator and another $50 or so to get another regulator for the propane tank. I will get some quick connects to make it easier to change between natural gas line in my garage and a griller propane tank for use in the pod.  Will order this and install next week.  I'll post back with results for how it works.   

I'll find out.  I have four propane tanks and I know I have to refill the gasoline tank after about 8 hours. No extra fuel tank for the gasoline. I suspect a propane tank will last at least a day or two....depending on the load.  I only use it to recharge the batteries on the pod.  With the current low price of gasoline under $2.00 per gallon, it probably costs less to run it on gasoline right now.  Even if it costs a little more, the advantage I see is not carrying gasoline around in a can to use for the small amount we use it while camping.  Also, the thing barely runs right now due to the gasoline going stale and not having stabilizer in the tank.  Need to clean out the carb by getting some good gasoline in it and run it a while before I convert it.  Main reason I got the generator is to keep the freezer running in case of a power failure and I have a natural gas hookup for that use.  Lost a freezer full of meat a few years ago......    

Thanks for the replies.  I will post back in a week or two after I get the tri-fuel generator conversion done and test it out under load using propane, natural gas and gasoline.
