Pros
- 14-50R and L14-30R outlets, so it feeds a 50 A transfer switch or an RV
- Enough for central air or a well pump plus a fridge and furnace
- Runs on gasoline or propane, so stored fuel never goes stale
- Shuts itself off if carbon monoxide builds up
Cons
- Over 220 lb, so it needs flat ground to wheel around
- Only two household outlets on the panel
- Not CARB compliant, so California buyers need a different model
- DuroMax has dropped it from its own store
