Interestingly enough, I had occasion to borrow a mates's PA-39 the other day to go bush in a hurry.
With only two on board plus out-and-back [sorry Owen!] fuel, the only way it could meet the trim requirement was to seat my wife in the middle seat. We had minimal overnight baggage and our usual 15l water drum right in the back.
This made the flare and touchdown just fine, plus the fact that my wife felt she'd spread out in First Class!
After 40 years of airline flying, I was able to use this aircraft to do my first GA CIR renewal following the endorsement and GNSS rating. It's a delight!!
G'day
