Gary,
This is my first time to the bulletin board. We had a Cessna T310 in Puerto Rico and Ecuador last winter/spring. If you still have a need, contact me at mschoder@aeromap.com or

Our Cessna T310 or 320 Skynights can do FL250 to FL280 depending on load and temperature. We have dual camera ports, non-pressurised, survey grade GPS or GPS/IMU positioning, as well as Zeiss FMC cameras, or DMSV digital remote sensing sensors. We operate in Alaska in May - October, and like to go to the Carribean, Central or South America in October - May seasons.
