Than you will always find small issues that you can't even name, but makes you leaving the vehicle smiling, or sad.
For example California Big Sur is a road that lot of RV owners call "white knuckle driving"
I drove it in 40' motorhome and it was "1 hand driving" for me.
The difference was that my motorhome was not one of those 40 footers build on 32 frame, but it was build on commercial Gillig chassis.
It cost more up front, but cost less later and makes you smiling between.
