Rob,
You can make anything work, depending on your tolerance to pain, suffering and over loading. Just look at the wide splay of opinions on here. Most civilians have a hard time accepting the truck's door jam numbers and don't believe those numbers apply to them. After being on here for 10 years, I have seen a lot, but not all, people decide, from bitter experience, that 1 and 2 series trucks are, in the long run, not up to the task. Which brings me to my only advice: Buy more truck than you think you will need. I have never, ever seen anyone on here that thought they bought too much truck. If there is someone, speak up and let us know how it worked out for you.
Off roading places unique stresses on the camper box because of the twisting of the frame underneath. Know how to deal with those stresses. Some truck brands twist more than others. A long bed twists more than a short bed.
Since you are a longtime lurker, you have read plenty of stories about what works and what doensn't. Sooner or later you just have to make that leap of faith and that you are pursuing the right equipment for the job.

Ours is on the left. Good for two. A BC-er is on the right. Good for 3 or 4 people, depending. Notice how we both took up two parking spaces. Hmmm?
