First, you and the inspector should be able to take as much time as you want and need to inspect the coach. This includes a test drive. After this, you negotiate with the dealer about what you want fixed or changed. When you come to an agreement, you inspect again to make sure the agreed upon updates are made. This is what we did when we purchased our used coach and we used an inspector. We had the inspector look at the coach before we were there since it was not close to us. The inspector looked at a lot of coaches before he found one that he thought would work.
