The DH8B (-200) will usually be able to accommodate a jumpseater from GUC. We are under no restrictions about bringing carry-on bags that have been gate-checked up into the cabin to help with weight issues. It was discussed in ground school as a tool to manage weight and balance issues.

I checked the paperwork for the first GUC-DEN flight today. The flight is booked full, but a jumpseater should be okay, so long as the number of checked and gate-checked bags is not crazy. The weight restriction is less than 1000 lbs below MTOW and the planned fuel is pretty low. An extra 1000 lbs of fuel could be carried without infringing on payload.
