If you are in the market for a pre-owned RV you know how much they are running for. Some are even around $150K.
So wouldn't it be wise to have an inspection performed on it before you purchase it? You would spend $500 plus on a home inspection right? RV's are no different than that of a home.
We inspect Motorhomes Class A & B and bumper and 5th wheel pull behinds INSIDE AND OUT!
