OK so I may have figured out a way to solve the limited outside storage issues. Hit me with any issue you see with this solution.
Since I posted I did realize I forgot there is a very small(maybe 2.5 to 3') outside storage at the front. Access door is forward of the first entry door. This is under the bunk wardrobe and is maybe 1.5' deep. Not much room in there. The bunk door opens up on the other side of the TT. You can swing the bottom bunk up and store bikes or whatever. This area is open to the inside of the TT. We were planning on using this for bikes while in transit. If we did not use it for bikes, we could partition the bottom of the lower bunk and that would solve the storage issue. We could even open up the wardrobe wall and make it a pass through. The bunk would still swing up and allow access to this new pass through from the inside if needed. All of this mod could easily be reversed if needed for resale etc. Maybe we could put a bike rack over the A frame and storage problem solved?
Here is a picture of the wardrobe, the lower section is where the outside storage is. You can also see under the bunk open to the TT. Second pic is with the bunk up and the bunk door from inside.
