I dont want to carry any cooking utensils (stove included), so dehydrated food wont work for me. So far I've planned cashews and some sort of trail mix to get me through, but thought a meal would be nice.

I get worried around west Texas. West of Ft Worth I would take the 180 to El Paso, then from there it looks like no civilization for 60 miles or more on highway 9 to 338 to I-10, but then again I dont know the area. Interstate travel is illegal in NM which by the route I have chosen I would be on it for less than 10 miles, maybe even just 4 if I take 80 instead of 338.
