I'd have to go with the Keystone Passport 199ML.
The problem with the R Vision is that the slide blocks the refrigerator when in. I can live without television, but don't want to extend the slide to reach the fridge when stopping for lunch. And that slide is very deep, especially compared to the Passport. While it creates a really nice sitting area (especially with the table removed), I have a distrust of any slide that is nearly as deep as the camper that is holding it up. The Keystone slide, being less deep, will weigh less and have fewer potential mechanical problems IMHO.
