I've had her 25 yrs though and love 'r dearly. Gets a little wheezy at some high CO and NM strips, but not bad. Flew her down to Haiti for the quake and hauled so much stuff the gear legs bowed. If you can shut the door... Just land softly.... :p
That's awesome, I bet that was quite the cross country....err.....ocean.......and it sounds a noble quest as well.
Definitely loaded ours up plenty of times, haha. Flown with even the float compartments full of meat and a moose rack jabbing me in the back of the head. Not to mention the occasional sketchy external load strapped to the floats. Luckily it's only a 45 min trip. With full tanks I'd never get off the water safely with only a 3,000ft lake there.
Thankfully don't do too much high altitude flying here, most all of our lakes/strips are down low. And also not a whole lot of heat/humidity so density is rarely too big of a concern. It's rare that I'm above 2200, even in the air. Weather, or more accurately a lack of weather information between destinations however, is a different story.
My father bought ours in 1985 (its a 76 A185F) and it has been in the family since so It is literally a family member. Been cruising around in it since I was -9 months old. He still flies on occasion himself at 76 years young. 6000 hours all in the bush.
