Airstreams are not exactly known for exterior storage. Twin bed models, including my 27FB, already have more options with multiple exterior storage compartments, one to each side under the twins. Still, more is always better, with a focus on improving flexibility of use.
The space under each twin is partitioned between interior under bed storage, and exterior storage. My goal was to improve flexibility of use by removing the rigid partition so to fit oversized items, either inside or outside.
Removed separator partition to open up the space. Also found a bonus space that was previously fully enclosed at the foot of the bed. I cut a 2" strip from the top of the partition to re-attach, to maintain support of the cabinetry.
Much better. Oversized items such as my Blackstone grill and some folding chairs now fit nicely in that side space.
