Congrats on your new rig; yeah - you're gonna buy it
I can't comment on the quality, but I can tell you that we went from tent camping to a 39' 5er. Intimidating? Yes, at first. But if you know the mechanics of backing a trailer, you just have to get used to the characteristics of the longer rig. The tunnels in the tidewater VA area create quite a pucker factor the first time or two, but it is amazing how quickly you get used to it. I worry more about low clearance (my height is 13'-6") than I do my length.
