In response to hugospro, he is right. A lot of stuff continually needs repaired on an RV.
If a person is not mechanically inclined, they will be spending a lot of time and money on small repairs. An RV is a house that is vibrating and shaking as it goes down the road. Shake a house for a while and it would have some problems. Most of the components in an RV are not manufactured by the RV company, they are purchased from outside suppliers. Sometimes if there is a problem with things like glue, screws, laminate, seals, upholstery, etc. the manufacturer has no way to know it until the units have been in service for a while. Also, if you ever watch these things being built with 20 people or more installing components at the same time it is amazing that more does not go wrong. Final inspection often has over 100 items that must be repaired before the RV is sent to the dealers.
If it is any comfort, I subscribe to Tiffin and Thor groups as well as Forest River, and RV's of all makes are the same. A friend of mine spent 400k on a high class RV and in the past 4 years has spent over 20k on repairs, and had a catastrophic engine compartment fire caused by a loose exhaust fitting that was covered under warranty after only 4k miles. So more money does not equal fewer repairs. My 2012 Georgetown 337XL with 32k miles on it has never been in a shop, but I have had to tighten, adjust and do minor repairs to may components over the past few years. The Winnebago, Rockwood, and Four Winds motor homes I owned previously were the same. So if you buy an RV you had better have a good set of tools of a lot of money for labor cost
