They may not have been built in the last 20 years, but wouldn't the
Piper 28's in the 140 and especially the 180 horsepower versions fit
into this group?

To answer that question for this thread just run the peformance numbers for
a 180hp SEL aircraft at gross in South Lake Tahoe on an summer day with OAT
90F. The poster talked about a family of 4 on 1000NM trips in the SW USA.
Even C182's are struggling in those conditions and I depart in Mornings or
evenings from that location.
