SBs were redesigned in 03 and they got a nice big basement. They also got wider taller and a lot heavier. They had the Morryde option starting in 03. The 31s were very popular - big enough to get most of the creature comforts. SB had problems with kitchen slides when they were first redesigned. They put the stove frig and tv in one slide and also went to a flat floor slide mechanism and that slide didn't hold up. I would probably pass if it's the flat floor kitchen slide. Later They cured it by going back to a conventional slide for the kitchen. The top entry step was in a pocket on that first redesign year and I've seen people trip and far clear out of their units. They definitely went thru a learning curve in 03/04. Avoid the flat floor kitchen slide and be aware of the pocket step are the two biggies. Craig
