Have not seen it before, but Uro camper looks nice, and lite too.
Friend who upgraded with Tundra brakes had 16 inch wheels without spacers. He used the 199mm S13WE brake calipers that he got from a junk yard, cleaned up and match painted to his truck. He said the only modification that he remembered making was to bend the dust shield some for the caliber to fit and drilling out the banjo bolt about 1/4 inch and says his braking has substantially improved- by about 1/3rd or more. I plan on doing the same modification when my brakes get bad if it will work with my 17 inch wheels.
Personally I like Firestone air bags better for some of the same reasons/problems that Hanson details on his build and because it is what the Baja racers use so I know it will hold up. I liked the adjustable shock upgrade he did. I also plan on doing that when mine weaken. The bags are supposed to enhance the springs, not pump up to ridiculous poundage and then go over jumps which I am sure could do some damage. I have about every option but AC on my fleet and fully loaded with water it is pretty heavy for the truck -have never needed to run over 35 pounds pressure in the bags.
Morocco is well worth doing. Went there on a Vanagon Syncro caravan many years ago and it was one of the most fun adventures ever. Sure hard on the Syncro though where we went. Hope you have a great time over there, lots of great camping all over Europe.
