Not familiar with the Shasta, but I'm about to buy a Wildwood from RVWholesalers. I just looked and they have 3 of the model you are looking for in stock. This is my 4th rig from them since Fall 2011- obviously I've been very happy with my buying experiences from them. I'd give them a call and ask for Kelly Tussing- this is the same person I've been buying from since my first rig. I'd be surprised if you don't save some money and have a better customer service experience. Good luck!
Before we bought our 2017 Cherokee 274dbh we looked at a few other brands which included both of those brands. I wasn't to impressed with the Shasta (at least the version we looked at). I actually put a deposit on a Wildwood before we purchased the Cherokee. The wild wood was nicer and nicer than the Shasta in my opinion. I was able to negotiate a good deal for ours being it was priced higher than the Wildwood. The honest selling point was the color schemes and it had nicer stock options, we liked the Cherokee better. Just my 2 cents.
