Undecided review
I purchased this generator on sale a while back and stored it away and never used it. Recently had a an opportunity to use and it didn’t go well. The generator constantly LEAKED gasoline the entire time it ran. I also was then afraid to try and use the propane side of things no I feel stuck because I’ve had the generator for such a long time and not sure where to look for help considering it’s out of warranty. This entire puddle is gas that leaked.
Runs quite has enough power to run my RV

Stable, powerful, quiet
Its lightweight but powerful for its size and extremely quiet. It came well packaged and the setup and startup was straightforward and easy. I have and will only run it on propane. I don't want to get it gummed up with gasoline.

Decent unit
Nice little mid power 120v generator with two 20 amp outlets and a TT30 30 amp outlet. Generator is nice in that you can fill it with gasoline and hook up the propane, and it will start on gasoline and when the gas is out, it will automatically switch to propane, which can give you about 24 hours of run time off 1 "fill up" (depending on load). Mine came with a NGK spark plug (many come with cheap plug that is junk). Unit is quiet and the display screen is nice. I do wish it showed actual watt...
