My "problem" is that a year after our RV was complete, and the same day the plans for a Pitts S1 arrived, my wife told me she was pregnant.
At around age five, he outgrew the baggage compartment so we are now in need of an extra seat. As much as I like the -10, it isn't in the budget.
Thus, I hope to check checked out in a T-tail Lance in the next month or two for those few times we need a backseat. If the currency requirements are onerous, then I'll at elsewhere.
Remember, you will still need additional renters insurance to cover the four seater.
