Why do I need to let the ROAM office know when and where I want to go? Can’t I just show up?

Must I pay a membership fee to join ROAM? If so, how much?

What kind of recreational vehicle (RV) must I have?  

How may I become a member of ROAM?

I have been helping churches and camps for years so why should I join ROAM?

In a nutshell, what is RV’s on a Mission (ROAM)?
