Hey Iggy, thank you very much for the feedback. I got the GTA number off of the info panel behind the driver seat, so perhaps that's a FR# too. It all started when we went to the RV show at Hershey and a sales guy asked us for all of our coach info. He questioned if it was an XL. Ours does not display the xl on the logo outside of the exterior door, just 350. It has the bigger chassis, larger rims, and most of the options you listed. We always thought it odd that our basement storage has no lights in any of the compartments...will have to add those. I have read of an earlier 2012 model line, so perhaps that is what we have. I have to say I really enjoy this Forum as we are new to the class A scene, and I am somewhat limited in what I am willing to do mechanically. We also have very little in the way of a reputable RV service center in our local area (Lehigh Valley PA), so this site can fill in some of the basics!
