BubbaTex, the Champion 3500/4000 generator is the most argued about generator on the internet.
it's been around for at least 5 years and is all over all the different RV forums.
you must be new to looking into a generator.
you'll have months of reading if you do a search on them, especially on RV.net where the Champion thread is its longest thread, nearly 1000 pages of posts.
the bottom line is that it is a very well made and supported, inexpensive generator that's perfect for boondocking and race events.
it, however, is not especially liked in campgrounds. it is much louder than Honda, Yamaha and other inverter generators.
but it is quieter than other open-framed contractor generators.
but for under $300, it will run most a/c's and has a 30amp RV outlet. it weighs over 100lbs. and needs a wheel kit. Champion supplies great customer service.
but, in my opinion, is too loud for campgrounds. i was going to buy one, based on price and reviews. but the DW said, "no generator unless it's the most quiet one made".
i listened to a Champion and then a Honda and a Yamaha inverter generators and i decided the Champion was wayyy too loud for campgrounds.
i suggest listening to both types before you decide.
