I'm glad I flew the Porter, Onan, but it's a dog compared with the Beaver!!!
Incidentally, forgetting to reset the elevator trim has cost lives; it got an electric trim because the pilot couldn't operate the trim and hold the stick forward at the same time. Now there's a mod out for an aural warning because even with the electric trim things were still going wrong!
DFC has also raised the issue of checklist philosophy. In commercial flying you find there are different checklists for different phases of flight like flow, challenge and response, read and do etc.
These take account of there being two crew but the philosophies are the same. Most relevant is to do the items on the list and then take the checklist and confirm that all is as it should be.
With regard to the complex types.
The ATR checklist A4 sheet folded vertically in half and printed both sides, pre-start to leaving aircraft.
Now the emergency checklist, that's a different matter!
