Stuck at work right now, but I'll see if I can post some pictures here later today. Might be best if you PM me your email address as well, just in case. I'll have to measure the interior width/length (unless someone else on the forum knows this; it's very much standard!).
You can find more information on the 17A on the following site. The only major difference between the standard 17A layout and mine is that mine has dinettes front and rear (ie- no fixed bed).
Hope that helps!
