I was going to suggest the Outback since the ones I’ve seen are very nice, but now that I compare your two models, I’d go with the Cougar.
1) The rooms partition off better in the Cougar: slider for front bedroom and narrower curtain for the rear.
2) Cougar is slightly shorter, slightly lighter. More isn’t always better.
3) Cougar kitchen counter has an extension leaf for more space.
4) Additional window in dining area.
Bonus points for your favorite dealer carrying the Cougar.
