RV gasoline life span in long term storage
Due to health problems our motorhome has been stored unused for over a year. How long does gasoline last before it goes bad?

Sorry to hear about your difficulties. Was any fuel stabilizer used prior to parking? If so, it’s probably OK, but I wouldn’t personally go past two years even with stabilizer.
If it was not treated, it depends on the conditions, temperature, humidity, how full the tank is. Over a year could be to the point of degrading already. If it was mine, I’d put some Techron fuel system cleaner and some octane boost in the tank and hope for the best. Probably that will get you through that gas and you can drive it out and get fresh gas.
It’s impossible to be certain of the situation until you get into it. Could be no problems; could need fuel filters, worst case it could need the tank dropped and drained.
