By the way, this new Onan built-in compact inverter generator will also be available for propane fuel, which are most commonly used on Class B and some B+ built on diesel-powered chassis (like Sprinter and Transit). Diesel generators tend to be more expensive and heavier, so RV manufacturers often use the 2,500 Watt LPG Onan generators on these smaller motorhomes.
As expected, greatest advantage of inverter generator in fuel savings is at light load. At full load there is no fuel consumption advantage.
Previous LPG 2500 Watt:
No load — 1.2 lb/hr
Half load — 1.6 lb/hr
Full load — 2.3 lb/hr
New Inverter LPG 2500 Watt:
No load — 0.77 lb/hr
Half load — 1.27 lb/hr
Full load — 2.31 lb/hr
