Hangar cost
IMO, the biggest "con" has not been mentioned yet, which is that if you get an RV you are most likely going to want to keep it in a hangar. This is a very significant expense, which cuts into all the other savings you achieve by acquiring an RV. There is a well-known poster on this forum who keeps his non-painted, polished aluminum RV outside, with a cover over the cabin area only I believe, apparently without a huge amount of obvious deterioration, so I suppose it can be done. But I think most owners of nicely painted and cared-for RVs keep them inside because they recognize keeping them outside will significantly degrade their aircraft's appearance and condition over time. In contrast, if you buy a production aircraft that, in many cases, has already been living outside for years, you are not going to suffer much incremental deterioration by continuing to leave it outside, and it costs a heck of a lot less than paying for a hangar. I'm happy with the RV I've owned for 20 years, but think prospective owners should be aware of and carefully consider this expense. I would be interested to hear the comments of people who have experience keeping them outside. Maybe there are some who disagree that RV's are generally made to live inside?
