I recently bought (2) WEN 2000W for $380 each @ Woot.com & the connection kit on Amazon. The WEN engine is a clone of the Yamaha, probably made in the same Chinese shop, and appear to be the same quality. I can pick-up one in each hand for a balanced walking load & I don't feel strained lifting one at a time into the truck.
Last week we boondocked at Assateague SP near the beach. Too cool for A/C so we only NEEDED one genny. However, having (2) meant we could use our coffee maker, electric skillet & wife's hair dryer vs. truly roughing it...
I only used about 1 gallon of gas per day in Eco Mode & we ran on batteries during quiet hours. Recently I swapped-out our RV fridge for a larger residential Whirlpool ($300) & love the extra space & efficiency. (Cools to <40 in 1 hour...) For now I just have (2) 12V marine batteries and a 2000W inverter ($100) which last throughout quiet hours.
