Thinking about buying a class c

We had to replace the fridge, roof AC unit, awning fabric, converter charger and have major fuel system work on the RV generator in our 2004 Class C at around the 10 year point. If you buy a 10 year old rig, expect some major repairs or replacements and factor that in with cost of insurance, registration, smog testing, tire and house battery replacements every 4-5 years. Owning any motorhome is a luxury. I've always thought that it might be more cost-effective to buy a 3 year old rig than a 10 year old one and either might be more cost effective than financing a new rig.
