If you want to believe Nick would never maintain an rv or its contents for 20 years, there's nothing wrong with that. However, on the reverse side, Nick could have easily learned his lesson after the first Airstream was destroyed by buying a new one in 2017, refurbishing it, and making sure that Airstream and all of the contents were well cared for, *this* time around. There are no hard and fast rules that, just because an rv is 20 years old, it has to look like it's been driven and parked all over the country for the past 20 years. If Nick has the money to buy one and then gut and have it refurbished, he has the money to keep it in shape for years to come. RVs are more popular than ever and so are the shops that sell, repair, and restore them.
The best way to frustrate a cyberbully is to ignore him.
