Did a little Googling...Plattsburgh and Elmira both had 4,000 when they hosted in the late 80s. Norwich hosted in late 90s and had a listed crowd of 4,733. That seems high for Kreitzberg but that's what the NCAA has listed.
So yes in D3 history there have been several sellouts with crowds of 4,000+ previously and crowds over 5,000+ in Lake Placid that weren't sold out because the size of the building. As Casey Stengel would say, you can look it up. It is easier to just make broad, sweeping statements though than spend 20 minutes checking.
No sense of history in Utica because the sun rises and sets on the Aud, apparently.
