I am so glad to see this kind of question. I believe the Flippac will be recognized as iconic in overland lexicon. Mine is on a 1st gen but am struggling with getting something with more amnesties for future trips. But I keep looking at the big rigs and remember all the Colorado trails we covered with the same abandon as a Jeep rented in Ouray.
*thumbs-up*
I have Wildernest on my 1st gen now...sure it has hardly any amenities, but love all the out of places it has taken me. Eventually I'll probably go the full on camper route...but just not yet. The better half has been getting on me to buy a newer truck, it is getting long in the tooth, we don't trust it anymore. The past 6 weeks, the fuel pump, clutch, and rear diff went out. She said to me, maybe it is time you retire that old truck and get a new one. Finally got off my butt, went and test drove an ACLB with the 4 cylinder today, had plenty of pep for me...actually surprised me a bit from all the flack the 2.7 gets.
I could make my Wildernest work, but it will look pretty cobbled on a brand new truck. I like the AT Habitat, but don't want to pay $10K, nor do I like that it flips to the rear of the vehicle. So that leaves the Flip Pac...they are hard to find, but not too high in price.
Do have a line on lowish mile 1st Gen, that we are going to look at this weekend, plus the Wildernest will swap right on over...so who knows???
