Good catch.
Personalty, I, me, myself, can't see why you would want FDII.
If you want that level of off road prowess why not get a more capable unit?
To me the FDI would be way more than ample, given my expectations of the vehicle, its height, articulation and etc. And my experiences with my FWD Patriot.
I drive a FWD Sport and over industrial and logging roads (for work) that many of you would consider off road. These are not the "mains" that tourists use to go camping on, these are the network of private roads built to get to the fish farm hatcheries, mills, chemical plants, mines, etc. in the bush. I drive them in rain, snow, dry, mud, dust,...they use blast rock to fill pot holes, not gravel. I've seen half ton trucks bend frames going into some of these "potholes". Some of my hills are 20* and greater.
Just to give some perspective...on a paved highway anything over 8* is marked as steep grade or somesuch and you are cautioned to gear down if in a big tractor trailer rig, etc. It is real uncommon, at least here, to have a road ascending or descending that is much over 10*. Its hard to stand on a 20* hill without beginning to feel like you are being pulled over.
Now I know there are places where the pass or mountain has a section that is steeper than that, but not covered in blast rock, no shoulders, no pull out lanes, no guard rails, no service station...in winter with the roadway covered in 2 inches of just under freezing snow and ice and just as you start down a fully loaded logging comes around the bend and starts up. And it is raining.
And my front wheel drive Patriot handles that just fine.
I'm waiting on a courier to bring my new cell phone..I've been getting by with a years old flip as my job requires satellite phone but this one has...gasp...a camera! 3.2 megapixels of raw snapshot taking power.
I'm going to take some snaps of these roads I drive on 5 days a week, see if you guys want to come up and play.
Anyway, lol, enough about me, find a nice FDI is what I'm saying, I'm sure its all you need.
Edit: after sleeping off the Friday night bottle(s) of wine with my sweetie at dinner, I see I may have mixed you up with dgree grade. Ours are labelled/signed in degree while (I think) the US uses percent. To clarify, that 20* hill I refer to is a 40% grade.
