Thinking about getting an Exaco Nelke Pro. 16mm triple wall poly, rubber seals, caulking. If I seal this thing up like Fort Knox, what sort of temperature difference might I expect between inside and outside during winter days?

Depends on how much direct sun there is, it will get nice and warm during the day. Once the sun goes down it will be the same temp as outside pretty fast though.
At night? Maybe 5°F above ambient, give or take. Insulation and sealing matters little if there is no heat source.
After the sun goes down, 0-1 degree. Sometimes, it is colder inside from transpiration even.
