My two are at the opposite end of the spectrum from Marc Cromme's green transport bike, which I love, by the way.
This is my 2013 Wrangler JK…
This is my 2003 Wrangler TJ…
My 6/4 CC and 6/4 F both fit in the back of the black 2013 with the rear seat removed. (And it has been removed, wrapped in plastic, and stored in a closet since about June of 2014.)
The older TJ is shorter and more narrow than the newer JK, so there is no room in the tiny bed for a tuba. However, the 345 and the Kurath both fit on the rear seat (individually!) and if I need both the BAT goes in the rear and the F goes up front with the bottom bow on the floor. This is not good, so I will take one of our threa beater Honda Accords if I need both horns, which (thankfully) is rare. The Mirafone 186 fits on the floor of the JK but won't fit in the TJ at all. If you lay it across the rear seat of the smaller jeep the bottom bow and the bell flare will contact the bare steel wheel wells. Bouncing around for two hours like that is bound to cause some bending in the bell's stack, so I won't even try this. It has never (and will never) go in either jeep. Again, Honda Accord FTW in such cases. Since the 186 is my go-to horn right now this means I take an Accord to work most days now.
