It will work very well for your RV. As he said, you dont want to run 2 heavy draw items at the same time. It probably has a twist lock plug design and you will need an adapter to connect it to your 30 amp RV cord.
I mounted my 3000 in the truck bed with a fan powered ventilated metal locking cover. It also has a remote start kit. When I run it a short time I dont worry about opening my cover lid. When I'm running it for longer times or when it's real warm out I will open the cover. Nice of him to give you the sweetest, quietest $2,000 generator on the market.
