The main drawback is the unit's 123.5-pound weight, which can be challenging to maneuver despite the wheel kit. Tri-fuel operation also introduces slightly more maintenance complexity than single-fuel alternatives. Additionally, the 5250-watt running output on gasoline is modest compared to some competitors at this price point, so verify it meets your specific power requirements before purchasing.
