Thx for the info and kind of what I thought, I really need to be where the RV is to see how many watts are required, but it is currently a couple thousand miles away and I was hoping to have the generator in hand when I matched up with the RV again. There is a used 2400 watt Yamaha unit for sale locally that I was thinking of, but it sounds like that it potentially could be too small? I could do the memorial day harbor freight 25% off sale as well and go a bit larger, but really want to keep noise and weight to a minimum.
