Pros
- Both L14-30R and L5-30R outlets, so it feeds a 240 V transfer switch or an RV
- Runs on gasoline or propane, so stored fuel never goes stale
- Enough for a well pump, furnace, fridge and a window AC at once
- Push-button start, and shuts itself off if carbon monoxide builds up
Cons
- Over 200 lb, so it needs flat ground to wheel around
- Propane run time is only about 5.5 hours per 20 lb tank
- Not CARB compliant, so California buyers need a different model
