I am satisfied to this point with this generator. The only issue is checking and changing the oil. The drain bolt is stuck to the extender piece so the whole thing comes out when removing the bolt. I believe I can break it lose with some channel locks at the next oil change. Be careful when removing the dipstick to check the oil because some will come out. Other than that, the unit has been excellent for our needs of powering a travel trailer
Aside from a couple of small issues upon opening the shipping carton the genset operated flawlessly. Enough power for our 5th wheel trailer and the noise suppression works well.
We've run a food trailer for several years and I've been breaking my back loading and unloading a larger (8750KW) generator. A friend suggested I try his Westinghouse iGen4500. We used his once and LOVED it so much we purchased our own. I can now lift the generator into the truck without ramps. The iGen4500 is so quiet, that we only place it 50' away from the trailer instead of 100' like the larger one. Most importantly, considering the current gas prices, we are using less gasoline. Our old generator would use 4+ gallons over six hours. The iGen4500 used only a little more than one gallon. We love our new Westinghouse iGen4500!
