I just can't see spending 150k for a FUSO/global conquer the world vehicle. I am really torn. I love the sportsmobile but it wont work for a vehicle to live out of for that length of time. I like the chinook, not sure what others are comparable. I love the idea of an ambulance, and I could build what I needed but I need it to have a bed, kitchen, and shower/toilet. I love the fact it's so solid, and I love the platforms. Not sure if the Eseries are big enough might step up, but I do want 4x4. My fear with them is the weight as with the fuso, I am guessing the easiest is a pickup with a slide in camper, but you have to go around, you can't secure the whole structure by being in it. Just gathering the facts. I've sorted through some of the ambo builds but holy cow its all over the place and most threads have over 100 pages.
