There's a smartphone app called TORQUE. The "Lite" version is free and the full version is a few dollars. Amazon and eBay are full of little joobers like this 
and I just bought one. Like many, I have found that "all OBD3 protocols" doesn't commit the Chinese to making an adapter that works for "every OB2 vehicle." OBD2 entered the scene in 1996 model years, but these cheapie adapters don't seem to support the early protocols even though they plug in and the LED lights up. My guess is that YES this cheapie will work on a "2008" RV. Particularly if you have a 2008 CHASSIS. If not, do what I'm doing and print an Amazon Return Label. Mine cost $11 Amazon Prime and there are many for much less. It seems that at about $40 you get into one that'll handle the older protocols.
Here's a breakdown of our four vehicles.
WORKS ON: 2006 Toyota, 2009 Nissan
DOES NOT: 1997 Ford, 2002 Ford
The TORQUE Site is very helpful, see their WIKI for overview and they have a Forum as well. There's discussion about which adapters work on what. The key seems to be that the cheapies work on the CAN/BUS editions of OBD2, which phased in during mid-2000's.
