Rv repairs shop

I didn't know if there's a special place where you can get your rv repairs? I am sure like cars shop there are some places who deal with Rv's problem. As I've known with one of our relatives who own an Rv he is the one who fix any problem of their Rv. He is really good about in any cars I'm sure he got the idea on dealing the Rv's problem. They use their Rv anywhere they travel and they like it cause they're bringing their whole house with them.
