Don't pay attention to the people that state that because you are concerned, RVing is not for you. It is not true. I am an avid RVer and have the same concerns. I purchased an older diesel coach 3 years ago and it seems like there is always something that needs to be done. These "somethings" are little things - I have not had any big issues. For example, I have a number of florescent fixtures that are acting oddly that I need to work open or replace. I have a latch that needs to be tightened.
However, when I think about all the great experiences I have had while RVing I would not have had any other way, I know that owning the RV is worth the upkeep. I know that without the RV, I would not have traveled like I have. I see too many people my age that just sit at home and get into a routine. While that may work for some, I want to keep active and learning and experiencing new things. I do not know a better way to do that than to go out in an RV. I do not want to look back with regrets and I know I would do that if I did not use the RV like I have.
There are pros and cons to everything. You need to decide whether you think the pros of RVing outweighs the cons. As has been stated, most people never have big problems with their RV. I can just say that it is wonderful to pull into some of the most beautiful places and sit outside and watch the sun go down.
