My parents have just made a similar decision, my step-father has just had his 91st birthday and decided that his chronic COPD means that everything is hard work, leaving him permanently out of breath so they've decided to give up the caravan while they still enjoy it, they don't want it to become a chore. He is the absolute definition of stubborn but having given in and had a motor mover fitted in 2019 and switched to a lightweight inflatable awning in 2022 it enabled them to carry on for a bit longer.
