Rich Folks* expect to be pampered so it's easy to convince them they need up to 5 air conditioners. You can hear the salesperson speaking to the other sales folks after the sale "...So I says to the guy you deserve to be comfortable so I'm adding 5 air conditioners and upgrading the generator to a 15KW model. You'll be the only RV'er in the campground that can freeze meat in your bedroom....and he bought it. I threw in the special exterior coating for free to sweeten the deal".
Us smart 5th wheel and TT owners know we can get by with one or two and have just as much fun as the rich crowd.
* if you can justify buying 5 Air conditioners for 500 square feet of room you must be rich.
