Thanks everyone for all your great suggestions. We decided to go with the Grand Design Reflection 337RLS. We pick it up on Saturday.
I will say the Columbus did have a lot of nice features Glitz) in it that I liked. The island was moveable, we used all the time. It had a resident Refrig. (I liked the size but not the hassle of tying all the pull out racks and doors) Also didn't like it only ran on power, not propane. Liked the toilet sprayer for cleaning. Liked the table that extended. The new one doesn't. It used smaller tanks so if need be you could exchange at store. Unfortunately, the quality of the unit itself was poor made.
So after reading up, looking at the reviews from Company and GD owners and listening to what people had to say we bought the GD. It's nice also and think it will be just right for our future traveling. Can't wait to get on the road. Thanks again for everyone's help. Deb
