Delivered when promised. Truck had lift gate. Driver rolled it into my garage with pallet jack. Robust packaging and banded to a skid. Works as intended with no issues. Surprisingly quiet. I run this on natural gas only. On first attempt to start, It started on 3rd try. When you initiate starting, it will crank for about 5 seconds then stop. I guess this protects the starter. Subsequent starts it fires right up. There is no plastic cover or electrical connection cable included. The 12' gas line hose included is 1/2” diameter. This is the best value I could find for anything comparable.

This thing is nice. I bought it because I have natural gas ram to the house. I'm very happy and only done the break in running my camper but have it to back the house up.

Generator was delivered on time and perfect condition and is everything I hoped for. The tri fuel is the only way to go.

Got this beauty just in time for hurricane Helen

best purchase in a while, well designed and made machine

This is a great i have only used it in gas mode. Runs over 8 hours with camper AC on 68. 30 amp camper using the 50 amp plug. Also my buddies generator with out of his camper ran a 30 amp cord from the 220 twist lock and now running his camper also. Very heavy left it in the back of my truck. Loaded it with my tractor .

Great generator used for over 200 hours, easy to use, overall quiet and provides a lot of power! Used on our food truck and at times ran for 72 hours straight with short breaks to refuel. Got it on a $750 samsclub discount great deal!

I have yet to use this generator in anger but I have run it once a month for 1/2 hour to test my whole house backup system for the last several months. I run 240 volts from the 50 amp plug to a 50 amp whole house interlock. When I got it, I ran it from a 100# propane can and it ran well on that. I have just installed a 3/4" NG QD on the side of my house (which a certified plumber hooked up and tested) and ran the generator this month on NG. I plan to use the propane can as a backup fuel source going forward. I have not tested the generator with gasoline yet. It starts right up from the propane but takes a bit to start from the NG line as I suspect it needs to purge more air from that line as it is larger (3/4" with 1/2" adapter) and longer (20 ft.). I was able to run my home's 3 ton AC unit (with soft start) this summer with this generator. About the highest steady load I have seen on it with NG so far is 5700 Watts. I had low idle On and the lights momentarily dimmed when my 4000 Watt water heater kicked on but the generator responded quickly and automatically bumped up the RPM to meet the demand.

Fuel efficiency is impressive I got several hours of run time on a single tank, and the noise level is surprisingly manageable compared to other generators in this class. The outlets are conveniently placed and include both 120 V and 240 V options, which made hooking up my tools and home circuits easy.

Only run for one hour break in so far but seems nice and is quiet. Only issue so far is when researching this before buying, the manual stated it was a floating neutral generator with an included bonding plug which is what I wanted for connection to my house as backup power. However, when it arrived it is a bonded neutral and there is no information on the Genmax FAQ page that the manual points you to on where the neutral to ground bond is that you need to remove. Genmax service also still thinks this model is neutral floating by default and I had to send them a picture of my front panel to show them that it said Neutral Bonded. They did not have any updated instructions for this model either.
