We got it at www.sunrisedecks.com/
. Online purchase and had it shipped. The website has a lot of pics (in fact a couple we submitted back to them). We actually purchased it when we still had our Challenger before we upgraded to the Seville.
It is easy to put together (~ 1/2 hr) and really works good, especially if you are going to be in one spot for a while. We don't set it up for overnite, although it is tempting.
I am new to this forum stuff, so not sure how to attach pics yet. Will work on that. Never to old to learn. (I hope)
