I really appreciate all of the positive feedback. I went over to Lowe's today and bought the Champion 4000W/3400W for $319.99 (they price matched the cheaper Camping World price). Not sure why the continuous wattage is 3400 instead of 3500 like the ones at Camping World.
I originally was looking at the Generac but saw a lot of negative reviews on it regarding them being hard to start, even when new. I've seen nothing but positive reviews, both here and online, on the Champions that are $100 cheaper for a comparable unit.
Again, thanks!
