3 oil changes and 250 hrs so far. Spark plug still in great shape and filter looks clean. I've used propane exclusively. managed to get just up to 8000 watts draw. impressive. I sometimes do have it trip, if im charging lithium battery bank at 5000w plus add another cross-load of 500w+. I guess that is reasonable though. This generator has a _3_ stage regulator. The usual 2 stage + DUCAR 230179. The DUCAR part is usually mounted on generator frames. If you try to hard-line this generator or use a different regulator assembly, it will vent non-stop and fail to start. Solution was to keep this DUCAR DPRA part (Westinghouse 60490020), by disconnecting the 2 stage regulator bits. Then you can use the 3/8 flare to connect to a 1000L torpedo tank (with normal 0.5psi reg). Despite the name, its not a hi/low side regulator, but It acts as a "vacuum" for the carburetor.

I've done my research and the 11000 tri fuel westinghouse is the best generator out there. Its heavy, so count on a 2 person lift when getting it set up. There are some helpful youtube videos out there from Gavins Garage and Mike Life. Both were super helpful in getting me to decide on the right one.

I bought this 2 months ago and as soon as I did, my power outages stopped. I think the generator made the power supply gremlins afraid of it! Seriously though, this thing is a LOT bigger than I thought it would be, BUT it is actually pretty easy to move and store once it is set up. The set up was very easy and well thought out. The engineering behind the setup really shows it is designed to be as easy as possible. My electrician is coming this weekend to add an outdoor inlet plug and system lockout. Hopefully I never have to use it, but I am thankful for the peace of mind owning my new generator.

Step by step instructions were very easy to follow. The only step I needed to look up on the internet was the location of the battery connector. Previous step had me put the access cover back on, but it needed to be removed again to access the battery. I have used the generator once since purchasing it and it started right up. Generator is powerful, steady/clean voltage and relatively quiet.

We are pleased with our purchase. The generator is loaded with thoughtful features. We are especially happy it came with a battery charger we can leave plugged in since we live in a bitter cold northern climate. We haven't had to rely on the generator yet, but I feel confident in its build quality.

I love this unit so far. It is quiet, easy to start and fits my applications to a tee. It would be nice it they give more mounting options for securing it to something. In my case I am mounting it on top of a generator stand on my travel trailer. I either have to strap it down or fabricate some mounts to secure it while in transport.

Purchased couple months ago and will use for whole home power during power outages. Everything was there for easy setup and after fueling with gas unit started right up. I have done test run and unit performed flawlessly under load. Would recommend for anyone looking for reliable backup power.

Quiet, Quiet, Quiet - love this generator so far. Easy to assemble, and clear directions for setup and startup. The User Manual needs to be updated to include that there's a mesh, plug type oil filter, where it's located and how to access it, but other than that it was pretty thorough.

I can only comment on my initial experience. I received model# 11027 undamaged and ready for assembly. I read the manual, filled it with oil, connected it to propane, and it started easily and ran smoothly. So far, so good. Once I have my electrician wire up my transfer switch, I will test it under load and report back here with a more detailed review.

I purchased this 2 weeks ago as an upgrade to power my house. I had the iGen 4500DF and loved it. So far the 11000TFC is great with all of the features I need. I haven't put it through its entire paces yet, but will do so shortly. I did contact customer care on a non-issue related matter and they were quick to respond and in the U.S.!! Such a pleasure.
