Hi There -
Coachmen is part of Forest River, but operates as its own entity at it's own location. I believe the motorized units are all built at one facility; folding trailers at another (If I'm correct). Their website is clearly still evolving and you'll have better luck "seeing" what's out there online by looking at the bigger dealerships that carry these products. Just by doing that, you'll see several paint schemes offered. Like many manufacturers, Coachmen tweaks colors, styles and upgrades throughout the year.
That Concord floorplan appears to be a new one for 2013. Specs vary online for height listed at 9'8" and also 10'8". This is likely due to whatever products they're putting on top of the roof (vents, covers, etc.).
Here is a video overview of the Concord (these are 2012 models highlighted), but at least you can get a basic idea. They've already upgraded different things (like the outside TV is now in the sidewall, not in that back storage area, etc.). Two trim lines; one is more basic, the other with a lot of upgrades. This video is from Motor Home Specialists in Texas (they are a big Coachmen dealer) and would be a great resource to call and ask questions.

Another big dealership to call and ask questions to is General RV (several locations: MI, FL, UT, etc.). They have a bunch of Concords on their website as well (including one lower-trim 280DS). All their specs here have the height for all models listed at 10'8":

Looks like the Concord is built both on Chevy and Ford chassis, too. Also might want to call Coachmen Directly (sales line: (800) 353-7383) to ask. If it's in the range of ~10' high, perhaps there's a way to customize what's on top of it (air conditioner, satellite dish, vents, etc) to get the height under your 10' mark. A dealer could also do this as well.
As far as how well they are made, in all honesty, I looked for three years before deciding on our Encounter. Looked at everything else in that market segment (and also above it). At just under a year of ownership, I would make this decision all over again. For all manufacturers, it seems like quality is dependent on whatever rig you happen to get and whatever team was on that day to build it. I've seen varying levels of quality in all brands at all pricepoints (and I have really, really looked out there). I'm not sure one brand is so far superior to another. Wish that were different, but it's not. What I have learned is that having a great dealer (who does SERVICING well - not just the sales part) helps a lot. Won't know that until you know that, however!
Hope this helps! It looks like a really nice rig!
