I am glad that RoadTrek finally has come out with a private bathroom in a RoadTrek 190, back in April 2004 I was in contact with Andrew Knowles at RoadTrek, he is no longer at RoadTrek. Every year I have been in contact with RoadTrek concerning a private or semi-private bathroom.
The new bathroom in the RT 190 is similar to the Leisure Travel Vans Free Flight, Kudos' to RoadTrek.
Here is a copy of an E-mail I received from Andrew Knowles

Good Morning Ron and Rose,
Thank you for your enquiry. We have indeed considered a separate bathroom facility. While this is not offered on our 2004 models we may offer this in the future. However, I cannot say exactly when that would be as we have our engineering resources are focused on our new 210 Popular and then on the Versatile version of the 210.
