We too compared Heartland Sundance vs Cougar.
We looked at the 3300RLB first and determined we needed the second bath, so we compared the 2998RB to the 298SAB ( I think, and am too lazy to check it
).
We felt that the attention to detail in the Sundance was better, I liked the optional big axles on this model. The bunk room felt more funtional, and the 1/2 bath was the selling pooint for us.
Now, our daughter is 20 months old, but we were trying to think ahead, so our bunk room has a single bunk and a gaucho bed/sofa, and in the main living area our dining room table converts, and our couch has a blow up. So if she ever has a few friends with us we will be fine.
The 1/2 bath is pricelss, we had 4 adults and 5 kids in the 2998RB last summer, and I was very happy that NO one used my bathroom
the 1/2 bath played its roll.
So to be fare..... you are on a Heartland website. The thing we liked about the Cougar was the self contained side bathroom up front.
We bought the Sundance
