Micheal, thanks for the mention of the Photobackpackers site, while I don't have a LF camera I have been toying with making some camera and lens wrap-like boxes. The site let me know I'm thinking in the right direction. I just got a order of neoprene to play with. Now if only I could find a clutter-free surface to work on.
And Nacio, I like the sherpa cart. I've been eying pet strollers on eBay. Right now I have a cheap second hand baby stroller with all the fabric stripped off, but it only does well on sidewalks.
Enjoy your travels!
