Not the same but I have one for my house that I use for hurricanes etc. Essentially I change the oil and check the gap on the sparc plug. It is the cleanest running, least maintenance requiring generator I have ever owned. If you run your generator only occasionally there is no comparison (you will never have a gummed up carb and the oil will look clean even when it needs to be changed). CO emissions are around 30% less. Significantly less smell from the exhaust due to 80% less particulate matter.
On the negative side if your generator will run for 8 hours on 5 gallons of gas it will run for about 6 hours on 5 gallons of LP (this will vary by generator but was my experience, the official numbers are that LP has 72% as much energy as gasoline per unit). When it is very cold outside you will burn more LP as the colder the gas gets the more dense it is.
You will need extra LP tanks, so carry extras and keep a map of fill stations. If you can move to 30# tanks (standard on TTs) I would do so. I use 40#s for everything now including my BBQ. Eventually I will get rid of all the 20#ers that people keep giving me. Grin.
And a quick size chart
20# = 5gal = standard for BBQ
30# = 7gal = standard for TT
40# = 10gal
