I purchased the unit to use while dry camping. I had just ordered a new Travel Trailer and wanted to have 110 and AC. I could not be happier. The unit is lightweight and more importantly quiet. It is said to have one of the longest run times per tank but I have not needed to run it more than a few hours at a time. I did purchase synthetic oil to use from the start,.....I am a believer.
Im still breaking it in, but started first pull,I plugged in a 5k air conditioner a box fan and ran a shop vac and was at 50% power. after a while of running motor was misfiring under no load a little but soon as I put a load on it it was smooth. Dont know why maybe spark plug or just needs to finish breaking in. will be using for back up power and misc, bought this unit because of reviews and ability to run 15k air conditioner,so far im very impressed.
