Ryan,

The Bearhawk is another possibility.   

Typically a four seater, but Jan Gutwein added a "third row" for his smaller kids, hence flying with six

160mph (250hp) is slower than your requirements, and with 70 gallons that 1000 mile range won't happen.
Still with a 2500# Gross, Empty around 1400# not a bad payload.    For me a 500 mile range is about my bladder limit, so at 160 vs 200 mph....  About 40 minutes difference doesn't break the bank.
