Pros
- Starts and runs a 15,000 BTU RV air conditioner, per Champion
- Both TT-30R and L5-30R outlets plug straight into a 30 A RV
- Shuts itself off if carbon monoxide builds up nearby
- Runs up to 14 hours on a tank at half load
Cons
- Gasoline only, no propane option
- Pull start only, no electric start
- No wheels, so it has to be carried at over 100 lb
- 120 V only, so it can’t feed a 240 V transfer switch
