short take off/ landing roll, steam gauges, limited range: not many options out there. bn2 islander/ trislander, twin otter?
go for even shorter fields with the caribou or the an-2 , both have lovely seam gauge pits. unfortunately, last time i flew it, it appears one of the ubiquitous garmins has shown up in in the caribou, but its at the rear of the center console and easily ignorable. An-2 allows selection of a pit with garmins or without, although its radio navigation can be limited if i remember right, and rumor has it the garmin version has a better flight model, oddly enough
