Please notice 2 points that are a trade between the LS and RB/MD
The LS has a larger main living space(no mid-bedroom) and the loft is deeper than the RB/MD.
The RB/MD has 2 rather separate, smaller living areas and a less deep loft (due to the cut-out for the sliding glass mid-door.
These points make the 2 floor plans fit different types of owners:
The LS is almost a direct replacement for the legacy Outlaw 3611, the original and best ever selling Class A ToyHauler...it is best suited for the owners and family that will not break-up into smaller groups (i.e. couples and families with young kids).
The RB/MD gives the owners separate spaces to split-up the groups (like Teens could occupy the mid-room with their own TV while adults enjoy the salon - main room, galley, dinette).
About the loft...we sleep, only in the loft and love it (he is early 50's and she is mid 40's). The loft is about 32" tall from floor to ceiling. We use a 8"deep memory-foam CalKing that almost fills the entire space. No, we can't sit upright in the loft, but a stack of pillows make watching TV very comfortable in the remaining clear space. And the loft is always clean and quiet because it is not within the pathway to/from the garage, like most toy haulers.
Best luck
