Harbor Freight doesn't have a quiet generator.
Very subjective statement... my two cents!!!
My HF 2200 watt Predator generator was much quieter than other Motor Home camper generators around me when staying at a non electric campground this past winter. It was quieter than 4 MH campers that parked next to me in 5 days.
That is my noise comparison. And I can move it further away with an extension cord, unlike built-in gensets in Mhomes that pollute the campsite area with noise right next to me.
As quiet as a Honda? NO, not close, but quiet enough, and less than 1/2 the cost for more available power. At idle, during the day, with wind blowing in the trees it is barely noticeable. I put 4 tanks of gas through mine in 5 days running 4-5 hours a day to keep fridge running on AC and recharge batteries. I turned on the Air Conditioner twice, just to see if it would work, and it did, with the HARD start Cap mod I did to my AC last fall.
For portable and affordable power check out the 2200/2500 watt Predator from HF and sign up for coupons that you might find that put the price around $400 instead of the normal $500.
