The main reason for my question about depreciation was this. I am thinking of buying an "upgraded" Class C or Super C. My current C is a 2004, but has only 17000 miles on it, and has most of the bells and whistles I want. The biggest things on my want list would be automatic levelers, "man-sized" shower, and possibly bedroom slide with more storage for clothes. However, if I simply buy a newer Class C I would be taking a huge hit on depreciation. My 10 year old rig will hold more of its value now than a much newer one. I have to decide if the upgrades I want are worth it, or just keep and enjoy the one I have. As I suspected, and you folks mostly confirmed, the vast majority of the lost value occurs in the first 3-4 years. Thanks for the help.
