When I worked in the factory, it was my job to fill all the tanks for the forklifts as well as do the oil changes and filters.
Some of the Toyota forklifts at my work place have close to 10,000 hrs and no engine work. Our place is really dusty too and they are still going.
I think it would be a neat conversion, I see a local landscape company with all their zero turns have propane tanks.
That would be one of those "rare" ones if it's a true factory option.
In the 14yrs I worked there I never saw a forklift require any major engine work and those. Drivers punished them mercilessly. Most of them were clarks.
