Chieftain or Navajo

[thrust clb]

Hello guys. I'm looking at buying either a Chieftain or a Navajo . I currently use an Aztec for cargo and some pax operation. Any operators out there care to give some feedback on the following questions:

1. Do the engines generally make it to TBO? (1800hours).

2. What is the realistic gps groundspeeds and fuel flow do you see at 8500 feet?

3. Are the undercarriage as robust as an aztec?

Thanks!
