I have looked and been in every mid bunk 5ver out there and we decided to go with the Sandpiper 371rebh. We were originally going for a loft but after walking into the 371 rebh we fell in love with the layout, it is the only mid bunk with this floor plan. Depending on how many people you plan on sleeping in the loft in our case just wasn't necessary. We have had ours for almost a year and have used it a ton with just a few minor issues. The quality was actually better than I was expecting I just know from buying several other trailers the build quality just isnt typically very good. We seriously consider the Columbus it had some features we really like and some we really hated. I would just go with whatever floorplan you like the best.
