A lot goes into how long a motorhome will last. According to RV Share, an RV can last about 20 years or 200,000 miles, depending on which comes first. But how well the recreational vehicle is taken care of can impact its lifespan. Also, its longevity may differ based on class.
For example, a Class A motorhome is the largest option. These RVs are like the size tour-buses. Instead of towing a trailer behind, you drive the entire beast. This is also the most expensive option. But anyways, a Class A Motorhome should make it to 200,000 miles with proper care.
