Isbram that sounds like some great ideas. Could you post a couple of pics?
x2 Always looking for more refinements (and reasons to tinker)
We have the oven option too so only the one bay under the counter and it's congested with the plumbing. Also, our single propane tank is on that side so that blocks off a lot of room in that area. We have the K2 so about 6" shorter than yours. Doesn't sound like much but there are some nuances different with the floor plan. We don't have the storage space next to the refrigerator, but do have a storage cabinet above the cassette toilet (because of the different propane tank placement).
The N/S bed with the storage under is great. Overall we have more storage than we have figured out how to use efficiently, so always looking for secondary storage ideas - shelving, containers, dividers etc. One thing that I'm starting to learn towards is to use the underbed storage less for clothes and more for things that are more likely to be needed only once set up (and somebody isn't sleeping). No access to it unless the top is up, and everybody is up and at 'em.
It's a constant learning and refinement process, figuring out the best places for things. There's enough space for the 2 of us, but it also makes it easy to over pack and put things in to places that you forgot you have (and probably don't need). We have the exterior storage boxes which are great for tools and messy items (small grill, etc) but also for collecting really heavy stuff. Starting to rethink what's really needed and put the whole thing on a diet. Went through a scale our last trip out, 11,000lbs, and still under GVWR.
The more you use it, the more you'll enjoy it and appreciate the choice you made.
