Terry,
I don't doubt there are many highly-modified D2's around. But do you know of any with portals? In fact, have you ever seen a 4WD with after-market portals?
They are as rare as hen's teeth. Have you stopped to think why?
Even within the narrow confines of the dedicated off-roader, there is a very small niche group who would need or consider them. And a D3 with 35" tyres would probably keep up with most of them even without portals - actually an RRS would be better, as it's a shorter wheelbase
If you're really considering driving that kind of terrain, the size and weight of a D3 (now an extra 6" further off the ground!!) wouldn't make it a practical vehicle to expend those kind of resources on. For the same or lesser cost, you could take an RRS, bob-tail it, remove the front plastic bumper cover and supporting structures, add a 2" body lift, cut back the wheel arches and fit 35" muddies. Add shortened HS rods, modify the camber and you're looking at around 6" of extra lift, without venturing into "hyper exended" angles or using portals.
Hmm - once mine's out of warranty, sounds like a project
Cheers,
Gordon
