Good topic. I bought a seat from Wise Guys in NY, one with a fold down arm rest; I've gotten pretty soft as I have aged. Your post made me think how much I depend on cup holders in my other truck and what I might do to fix this problem. If you remember back in the early 70's, as cup holders were introduced in new cars as an option and standard equipment in luxury cars, the aftermarket came out with add-on cup holders. I remember the ones that snapped down on the armrest and on the tranny hump in the floor.
