Pros
  • Runs on gasoline or propane, with the hose included
  • Push-button start
  • Runs up to 14 hours on gas, or almost a day on a 20 lb propane tank
  • RV plug built in, plus wheels and a handle
Cons
  • About 100 lb, so lifting it takes two people
  • No 240V outlet, so it can’t feed a typical home transfer switch
  • Costs more on Amazon than the gas-only remote-start version
