We ordered a 3010DS 11/4/17 and it was at the dealer early - mid January. We didn't actually pick it up until the weather was good enough to drive it back, but we did complete the sale first. I checked prices with about 5 dealers on the internet and the closest dealer had the best deal, I think maybe $200 dollar difference, but could have paid thousands more. I would expect that you get a 2020 because you are ordering. Good idea to get the options you want, you can spec those all out to get a firm quote. The bigger A/C does a good job. Swivel passenger seat is nice, but a PIA to get used to working. Recommend a level mate pro
because if you are more than 5 or 6" out of level on any corner/side, the autoleveler's wont level. Class C is harder to level than a TT, even with autolevelers but the cell phone telling you where you're out of kilter makes it manageable. Filling the fresh water tank was frustrating until I got under the bed and supported the hose so it ran down, not down, then up then down. Some other minor defects.
Overall we really like it and are pleased. Really like the kitchen. Get the double fridge, it's nice.
