had propane gen set in my class a when i first bought it. Had hard time always finding propane on the road. had to always ask some one where to find it in small towns. then leave main high way looking for it and it was a real pain.
Finally had enough of that sold my propane gen set and bought a 8KW diesel cat generator. never had to look for propane again. The diesel was much more economical to run also. it only used 1/3 gallon per hour running 2 ac units.
I had to shoe horn it into propane gen set space but it fit like a glove when I finished.
Go diesel forget the propane. Been there done that.....!!!!!
the salesmen will tell you not to worry....!!!! "worry "
