Welcome, to the forum!
I just got my Cougar 30RKS we love ours. So far I am impressed. And LOL the extra storage I packed so much stuff our first trip (newbie) the storage space is really amazing.
On delivery our sensor was bad showed the grey tank full and it was not. 2-4 weeks to get a new one. Will post in another thread if anyone had that issue.
Best wishes on your new Cougar!!!!
