Coupla years ago, when I broke my leg in WA, I won a ticket on the World’s Most Exclusive Airline: RFDS.
SWMBO was left to drive Girt 550km to Perth — and lash down the car on the trailer as well as emptying the black tank — neither of which she had done before.

Fellow campers helped with both, but they couldn’t find the macerator pump switch!
While heavily under the influence of painkillers, preparing for surgery, I had to explain over the phone where it was concealed.

After I was discharged, we held practice sessions so she could handle both if I should happen to be incapacitated again.
