This is also in my plans once we are done with the Americas, in 2 years. I have been toying with the idea of shipping my 2007 F350 6.0 diesel with my Travel Lite popup camper, but for the same reasons you raise, I scrapped my plan. I will be looking instead for a much smaller vehicle like a camperized van, but I really like having 4x4 because eventually, I'd like to continue toward Central Asia, so my options are limited in my budget range. A Sprinter would be nice but the price for a 4x4 conversion is prohibitive, so I am looking at the much smaller Mitsubishi Delica, Toyota Hiace, or something similar that has a gas engine. Less room but more versatile and agile, and I could easily build a sleeping platform, storage boxes, stove/sink etc. for under $1000.
