We own a Big Country and absolutely love it but I agree with Jim, it comes down to personal taste and what amenities you want. For us, the decision was made by my love of the rear kitchen in the 3690SL and my husband's love of separate/distinct areas...e.i. - living room area, kitchen area....not all in one. One of my favorite features of my coach is I get to welcome my guests into my living room first instead of the kitchen. The first coach that my husband and I agreed on was a Big Horn (don't remember which one) but then I found the 3690SL layout on the Heartland website and loved it especially after walking through it. We continued to look at other floor plans but kept coming back to this one. Look at all the great options of each coach, tour as many as you can, and then make the decision based on your needs. Hope this is helps you, Buckeye!
BTW, I love your signature line!
