We run a Yamaha 3000ISEB and run 15k A/C and microwave without issue. Mine is always in the back of the truck, so weight is not an issue. But that is not true for everyone. If I had to take them in and out with regularity, I would have bought 2 2000's. But then you have twice the maintenance. Each has their advantages.
