Pros
- Legal to buy in California, unlike most open-frame generators
- Runs on gasoline or propane, so stored fuel never goes stale
- TT-30R and L5-30R outlets plug straight into a 30 A RV
- Runs about 14 hours on a tank at half load
- Shuts itself off if carbon monoxide builds up nearby
Cons
- 120 V only, so it can’t feed a 240 V transfer switch
- Pull start only, and wheels cost extra
