To convert a standard outdoor RV vent to a Newell type vent would require some custom work.  Remember that a Newell has aluminum side panels rather than fiberglass so the vent structure would have to be different.  I can attempt to take a photo looking up inside the vent at the choke cable connector if you would like.

Thank you for offering to do that!  That would be very helpful to have a picture of that angle, and how it all works together.  I'm going to talk to Xtreme Paint & Graphics and see if they think this is possible on a Foretravel, and your picture would be great to have to show them. 

On a side note, we've met before.  Back in 2010, my better half and I spent the afternoon and evening with you and your wife in your coach, while you were camped out in Austin.  We were very seriously considering a Newell, and lived in Houston at the time, when you invited us up for a visit. You were the first people to ever invite us into their coach and show us what it is like to fulltime.
