I am getting ready to place my order for a new 317RST and would like to know any 317/337 owner's thoughts on the need for the second A/C unit in the bedroom. The area rep for the south-east told me that at 34'11" and living in southern Alabama we are on the edge as far as needing the second A/C. We plan to spend a lot of time in south Florida and am wondering if anyone has experience spending the summer months with or without the second A/C. Thanks.
