Just a thought.
If the floor plan for that trailer has everything you want EXCEPT at least a single swivel rocker, why not consider buying that trailer AND a swivel rocker. Our V Lite came with two swivel rockers rather than the recliners, which we would have preferred, and they are small and don't take up a lot of room. It should be a fairly simple matter to figure out how to leash a single chair in place during travel, and while the Murphy bed is up, there is plenty of space for the chair, and when the bed is down and the kitchen counter extension is down, the chair could sit between the kitchen and dinette. Might be too big, but if there is still walk space between the bed and bath, it seems like it could work. It would be even easier if you got the table and chairs rather than the dinette, although you would lose a good amount of storage under the dinette seats. In any case, that IS a REALLY nice floor plan for two people...very close to ideal!
