When a vehicle is used as a daily driver or just locally, then comparing repair costs vs monthly payments on a new vehicle makes good sense. But I take a different view on tow vehicles, what 'cost' do you put on break downs while towing? Yes, brand new tow vehicles can break down on the highway also. But with a TV out of warranty the issue is just more complicated. And since we are talking about RVs, if the owner feels even the slightest bit uncomfortable about towing, THAT is the reason to get rid of it. RVing is not about the most cost effective action, but about what is the most satisfying actions. Even with my volunteer activities, I could save a boat load of money by doing work locally and not RVing at all. Anyway, each of us have to answer the question individually.
