Ok, I went & did some measuring after Josephs sweet schematics got me thinking. Dark Blue or Red would barely fit, but neither would work on the inside, and the foot of the jack would stick out awkwardly. It's only 43" from floor to cieling so yellow & green are out unless I cut down the jack & Handle. Green would tricky with the air shock & yellow with the battery (been thinking about moving that anyway though). I could turn yellow about 45 degrees and stick it in there at an angle, but it would kill a good chunk of the cargo room behind the seat which is current foll of two tool tupperwares...
Light blue might have some potential, though. It would probably stick out too much on each side and catch crap if it was just like you drew it, but I could probably rotate it 75 or 90 degrees it would barely overhang the back of the tire. I would need to modify the spare tire "handle" to attach the jack and change the angle. Perhaps cut it off, go with slightly larger tube and stick a couple bolts through?
