We have a 2015 TSBH, and for us it works fine. We considered the BHDS but went with the TSBH for one main reason: the bunk room. It's huge. The thing that tilted us to the TSBH was the bunk room. The tv in the BHDS is under one of the bunks, so if the kids want to watch a little tv before bed, someone is left out. With both bunks sliding out in the TSBH, and the tv in the middle, they can both see the tv. Plus all the storage in the bunk room gave my wife more room to store sheets and towels.
We got the fiberglass siding with frameless windows. The windows don't open as much as a framed window, but for warm temps, they provide enough air flow. If it's hot and or humid, it's AC time anyway.
Another consideration was the bathroom. I do like the outside access in the BHDS, but the vanity top is bigger in the TSBH... more room for toiletries.
Tow vehicle is a 2500 Dodge, Hemi, 4.10 gears. I wouldn't tow long distances with less than a 2500.
If you're still with me, the bottom line is, find a layout that fits your family. It may take awhile, but it's out there. Good luck.
