We are considering touring South America (specially Chile and Argentina) and later doing the Panamericana all the way to Alaska on a travel trailer. Main reason is that we are able to get a Nissan D22 Diesel double-cab 4x4 plus a Palomini 177BH for less than half the price...
PSA: I've been waiting for the OP to post Part 3 here in ExPo somewhere... and only today realized that he posted it (and Part 4!) in his new site:
Thanks for the heads-up, your truck+camper looks great... unfortunately as we plan to live in our future RV fulltime, it's just too small for us.
Good luck in selling it, tho... I'm sure it will make its future buyer very happy!
Du & Nica.
