Most of my trips are solo these days which has allowed me to lighten considerably.
My work schedule equals unannounced trips and I typically leave the IGT gear home and take the Jetboil and a backpacking meal and eat odds and ends during the day.
I've switched from Big directors chairs to an Alite Mantis chair, trading my 63 qt ARB for a 50Qt ARB, and bought a softopper so that I can sleep in my short bed tacoma.
Eventually I'll build a sleeping platform, but still working on the design.
Granted the East Coast is not exactly deserted or open.
