For the record, Coachmen is very much alive and well, and has been around since the mid-60s. They are a small manufacturer and build a very competitive, albeit value brand, of coach. Their parent company changed hands a few years ago to Berkshire Hathaway (and they're considered a division of Forrest River), but they still operate as "Coachmen".
We are coming up on 2 years with ours bought new, and have not had the "issues" that so many others describe all over the 'net (although I'm afraid of jinxing myself now by saying that out loud, LOL!
Ours has a ton of upgrades, rides very well and we are very happy with our purchase. We did look at Winnies too as part of our search, but ended up with our particular model Encounter, which has one of the best closed-for-travel floorplans I've come across. It has, and is, serving us well.
One thing that worked for me is that we did buy off the lot so that I could go over every nook and cranny myself of the actual unit we bought. One thing that stood out among brands while we were searching various rigs is the quality control among the very same units. Some were put together well; others not so well (same year, same manufacturer). Shouldn't be that way, but we encountered that in several different rigs built by the same manufacturer.
You can't go wrong with either brand, so find the one that fits you best! They both have their own pluses and minuses, so it truly is a subjective decision!
Best of luck to you -
