Pros
- Runs on natural gas from the house line, so it never needs refueling in a long outage
- A big 13.2 gal tank runs about 12 hours at half load on gasoline
- L14-30R, L5-30R and 14-50R outlets cover almost any transfer switch or RV cord
- Starts from a remote, and shuts itself off if carbon monoxide builds up
- Five-year warranty, longer than most rivals
Cons
- About 360 lb, so it is hard to move without a paved path
- Louder than smaller DuroMax models, at 78 dB
- Not CARB compliant, so California buyers need the XP15000HXT+
- Only sold as a pre-order from DuroMax right now
