Welcome to the Newmar forum & irv2.
In the
Quick Tips link you have a
COM_NET link that will give you info on your coach.
In QT there is also
info on your slide system, not sure what your problem was with slides but I have 8 year old controls without problems.
What was your problem with slides?
Jacks should work off just your batteries, but they are a problem.
Enjoy the forums and do post often.
