Difference between Cruiser RV Shadow, MPG & Fun Finder?

We're getting ready to purchase the MPG 2120RB. Saw it at the RV show last weekend. Sold our other RV last night. They're picking up tonight. It's just my husband and I so we're downsizing. Never used our couch in the last RV so we decided to do without one this time and go for more kitchen space. We don't watch a lot of TV except in the evening. We're usually outside.
