Thank you to all of you who have replied. This is all great information, especially the info about seeing the maintenance records and spec sheet. I have rv’d for over 50 years with my husband and bought the casita after he passed. I have used it extensively for the past two years, putting a ton of miles on it. So I think i have proved to myself that i am capable and able to maintain an rv and will use it. Onward and upward!
