There are many places in the world where a roof rack is really the only option for expeditions, due to the road conditions. But in North America, where both options are viable, there tends to be a lot of differing opinions. There's been threads in the past favoring one or the other, so I'd like to condense it back to a single thread for the archives, and hear what you have to say. FWIW, I have both, an INTI expedition roof rack and a modified ex-military M416 1/4 ton trailer. Both have their uses, but I think the decision to use one or the other is based on the condition of the terrain and the distances I will travel. Lot's of pro's and con's, let's hear them!
