It takes a lot of research, looking, and 'tire kicking' to determine what works for.....you.
We all have our own opinions and favorites, but that is not necessarily the right choice for....you.
We all have different needs. There is a lot to choose from.
At the end of the day it is too broad of a subject for anyone to simply tell you what is best. What one person deems poor quality from one manufacturer may be perfectly acceptable to the next person.
Typically, you just have to figure that out for yourself.
My advice would be for you to go to a few RV shows, if there are any in your area. Or, go to some RV dealers and check out the inventory. Take your time, and develop a critical eye.
