I have a 45 ft. diesel Class A Motorhome I purchased 20 years ago for $200,000. The motorhome I purchase 20 years ago is a low mileage (50,000 miles) and is a diesel. Diesel engine motorhomes are more expensive and sturdier than gas powered motorhomes. The motorhome I purchased was used when I purchased it. The coach has been sitting for the past 10 years and needs to be fully checked out mechanically. I was thinking about trading the motorhome for a newer model with slides. However, I heard how fast motorhomes depreciate. I heard motorhomes depreciate and lose their values faster than boats. I also heard banks and finance companies often do not care to finance motorhomes older than ten years old. Is it better to renovate my current RV or buy a new motorhome and sell mine.
