Took our 2015 2109s to Ludington, MI for 16 days. Towed just fine.
I think that the 2109s is a good size for 2 people, we brought everything that we needed. I'm sure a larger one would hold more and we would fill every space. I definitely prefer the sofa over a dinette. Now as to that monster of a table. Many have mentioned that they replace it with a folding lifetime or similar, I would like to but the DW likes it (she doesn't have to move it). I did find one positive use for it, it worked well as an anchor for a bike stand I bought at lowes (
Shop Blue Hawk Heavy-Duty Bike Stand at Lowes.com). A couple of bungees kept the bikes stable.
Since this was an upgrade from a pup, it was sure nice to not battle the bugs that invariably sneak in a pup. Watching a dvd on a rainy night was nice too. The DW found some nice towel racks for the bathroom door.
The two problems I did experience (going back to the dealer for these), were hitching and the TV. Getting it hitched (the lock down piece or whatever it is called) was a chore. A couple times I had to rock back and forth with the SUV to get it to drop. I'm guessing the ball is at a slight angle. Works fine in the driveway. The TV gets nothing on cable. Tried it at home also to no avail. TV works when removed and hooked directly to cable. I'm guessing something isn't connected or connected right in the wiring. Over the air was useless up there also, I am able to bring in about 8 channels at home in my driveway, but nothing up there. It was odd since the next camper over had a similar antenna and they were watching TV.
What would/will I change? I would replace those storage door locks with something that works smoother and would add a latch. No need to lock those doors sometimes, but you have to otherwise it is left with a gap for critters and rain to get in. I would add some kind of support to hold up the under bed storage top up while you rooting around in there. I wish it had a stainless steel sink instead of plastic. We are used to sticking hot pans in the sink to cool down.
So far I'm happy with the choice we made. I had 5 people stop and ask about it and 3 that looked inside, that was nice.
