Since the RV only has 2by2's you really could not go horizontal with the vent stack (tying it in with the existing one) without structural weakening of the walls. Which now means you must go threw the roof with another vent stack.

On edit:
Also just hand tighten it. Most the time it is impossible to get a wrench in there, and hand tighten is all it really needs.
