I put storage pouches in too, very expensive but fairly handy Stowmate, they really work excellent, I might consider one more for by the bed.
One thing I just did was to expand my options a bit on the overhead. I installed several little D-rings in an area that allows me to either suspend a light duty net or hang my shower curtain which secures onto a collapsable wash basin made of foldable water bags. I can then take a sponge bath inside when it is nasty out, which is has been for the last week on the road.
I keep a running list on my iPhone of both fixes and needed items for when I feel like tackling them. That way, when I am near a larger town with good supplies, I can get some of them.
It's the little things that bog you down at times, like needing both a cushion and floor brush ( mud ).
This road trip has been the longest sustained yet, over two weeks and things are going well. I head home this week for a few days and then out I go for a month.
Off to Wyoming again...
