Nothing I can help you with really... You are far and above more organized than I am!
I carry all that I need, and I find I still take way too much stuff that I never use, but glad I have it if it need it!
Most of my stuff goes in the bed of the truck. I have a flip top soft tonneau cover and a bed rug and a 6.5' bed and it holds all my "just in case" stuff.
I store my sewer hose in the rear bumper, the water hoses go in the front storage of the trailer along with all the level boards and whatever else goes in there!
The front queen bed lifts up for a lot of storage, but now that's just for stuff that only gets used "as needed". We used to put the pair of folding lounge chairs under the bed, but now just stack them on one side of the bed, since we always use them, they just come out first and go in last.
Don't have to lift that bed up unless we need whatever is now stored under there.. (for some of that stuff that I never use, but glad I have it if it need it!)
I carry way too many tools, jack stands, floor jack, bottle jack, etc, etc... and still have room in the bed of the truck!
Anyway, it's always good to share information, as I've taken quite a few 'tips' from members here and seeing what others do while out in the field and I've helped many a camper out there with the extra stuff I carry with my "just in case stuff".. :)
