When I decided to look for a new coach, true to the Engineer I am, I did a lot of research. I researched makes, models, reputations, costs, floor plans, sizes, weights, capacities, engines, chassis, and so forth. I considered convenience, reliability and experience, as well as trust, in selecting a dealer for service, which also affected my choice of brands. I considered what I could fit into my driveway, my street and my neighborhood. When I finally decided on a particular make and model, I researched options. I based my decisions on my 19 years with my old unit, my experiences, what I liked, what I didn't like, what I purchased for it, what I would have liked to purchase, and what I would have liked to have if I were starting over, which I am. I also considered when and where I camp, including typical heat, cold, noise, parking/leveling and privacy issues, as well as driving and backing experiences, sleeping options, visibility, my pets, and finally comments from members of forums like this one. One of the options I considered long and hard was dual pane windows. I ultimately decided that, for the types of camping that I did, and what benefits I might gain from them, for me (and I emphasize that's for me), the cost just didn't justify them. What struck me (but certainly didn't surprise me), however, were the sheer numbers of threads and posts on the subject, with a wide range of opinions, pro and con. I haven't seen a poll on the subject, however and so, just out of sheer curiosity (No, I don't have any cats
) I thought I would try one. I am starting with 5 choices (including don't know/no opinion), but please let me know if I should add any others (and please, no nasty comments; remember, this is each person's opinion/experience, and your experience may vary).
