Based upon numerous handling issues discussed on this forum over the years, I am of the opinion that the RT 200 handling is as good as you will find in any van and of course this is due to the excellent quality of the Chevy 3500 chassis.
Contrary to other RT owners, we have never experienced a window leak, and this includes the rear window.
The dump hose is directly under the driver's side door step and is easily accessible.
As for the shower pan issue, we never shower in the van, but stay in camp grounds with a shower facility as an alternative, which eliminates the need for a shower curtain and having to remove the floor carpeting.
We are very pleased with our 2000 RT200 Popular.
