Heh after reading this thread it has me looking at my Odyssey in a new light. I have driven the Fits before but being 6'2 and a preference for stick shifts in small vehicles..don't go so well in a Fit with its cramped pedal area. Thanks for thinking outside the box and inspiring others to do the same.
Minivans would meet a lot of peoples needs as an adventure vehicle. For work I ran an awd caravan to super remote places throughout the country and it never got stuck or got a flat. The smooth floor and sliding doors made for an awesome place to be during bad weather. 1 time I had to *gasp* walk an extra mile to a trailhead but that is literally the only time it didn't work. Copious amounts of throttle were needed in certain situations but it held up fine.
The pedal area in the Fit is pretty cramped, but it can also heel toe. Trade offs I spose'
I did drive my Monty (first time it's been anywhere in a month) the other day on a 200 mile part dirt and pulled 23mpg which is really quite decent for a 4wd on 32's but I could have just as easily taken the Fit and probably will next time.
At this point the only reason I still have the Monty is nostalgia, it has a hitch, and the fact I would be lucky to get 4k for it even though it's minty.
