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
- Push-button start and wheels make it easy for one person
- Shuts itself off if carbon monoxide builds up nearby
Cons
- 120 V only, so it can’t feed a 240 V transfer switch
- Small 4.7 gal tank for a home backup unit

#4 in SmallFull review
A small dual-fuel generator with remote start for an RV or for a fridge, lights and a sump pump in an outage. Worth the step up from the pull-start WGen3600DFcv if you want to start it from indoors.
