Amazing generator
My friend purchased one of these several years ago and I had to have one. It’s so quiet it doesn’t affect anyone at our campsite when camping. Starts fist try every time. It’s a work horse for sure!

Super fast shipping
Love this unit, the handle the lite 98 lbs is very manageable. The remote start is a great feature also. It’s very quiet. I now have owned this since Dec. this unit has ran every night when temps drop below 20 degrees. With temps 15 below zero on many nights this started and ran flawless.aThis has been a job saver for me, I can't say enough.

Powerful generator, great for RV owners.
Love this thing, travels in the bed of my truck, the remote start is an awesome feature. Plugged into my camper overnight no need to go outside to start on a cold wet morning. Great product. Would highly recommend to other RV owners.

Quite upset
I bought this generator and it never worked from the time I took it out of the box. Of course I can't send it back because it's had fuel and oil in it. So I was told to take it to my nearest Cummins dealer which is 50+ miles away, which is where it has been for the last almost 4 weeks. Sitting with 0hrs and now I'm being told we're waiting on warranty for an answer on what their going to do. That being said I paid $1200 for a paperweight I have never been able to use.

Tried and true
I bought a Generac non-inverted 8500W EFI model from Costco and it wouldn't start so I returned it. Decided to give the Cummins a try. It's not the latest design, but right out of the box (after adding oil and gas) it started right up. It's so quiet, relatively speaking (it's not going to be the gathering place at your parties) and just purrs along. They don't want you running more than 50% load until it's ran for 5 hours, so I let mine run to that point before hooking it up to my 5th wheel. Turns out my 50A 5th wheel doesn't even use 50%, at least without running AC which I didn't try. My normal hookup is only 30A, so I have no concerns with this generator being able to supply my trailer. In fact, my voltage stays up at 120 while running on the generator, whereas it drops badly when running on the park power. Changing the oil is a bit of a challenge. The body panel that covers the oil area for some reason does not line up with the oil drain plug and it's a very tight space, so it's extremely difficult to get any kind of wrench on it. I just bought a swivel head ratcheting box wrench to hopefully reach it easier in the future. I love the luggage-style handle that lets you move it around easily. I'm in the gravel and on uneven ground, so a 4 wheel setup is a problem. Tilting it up by the handle and rolling it on 2 wheels works very well. I'm very happy with the purchase.

Seems to be a good quality generator so far.
The product was delivered on time, but the battery compartment door waa dislodged during shipping and ended to inside of the generator. This was most likely due to the battery not being hooked down, as the battery was also loose in the box. So far the generator has started and ran for about 1 hour. It was easy to setup and get going. It runs very smooth and quiet. I would recommend generator. No complaints so far.
