For me the HQ19 is large! I was leaning more toward the 15 but also considering the 19 perhaps as a more family-friendly size. I agree there are fewer areas to bring such a large brick into but here in Montana there are plenty of options to get off-road where a solid suspension is needed, off-grid capabilities a must, and protection from the cold is appreciated outside of the 3 summer months. It's harder than I thought to find a pull behind that checks all those boxes and of course, nothing in the BS line will withstand sub-freezing temperatures regardless of the shoddy quality.
Anyway, after this thread and talking to a couple of dealers who have dropped BS due to poor quality control, I have moved on from this manufacturer. The search continues!
