Diesel Bombers - I don own a truck yet

Over the last year or so i have eliminated all trucks except for the Dodge 5.9 Cummins , 04 to 07 unless a real nice earlier one comes along. I live in Hemet Ca and work in central and northern Ca on water projects, if it doesnt rain soon there wont be any work. Most of my driving will be freeway on days that i come home, once every 3 weeks or so. I need 4x4 for the job sites when it rains, again ?? and I need something to tow my trailer, 8000lb empty, when moving to different work locations.

I am 66, not retired, so an auto tranny is my choice just for convenience. I am home for about 6 weeks till the next project starts in Patterson and am really pushing looking from a truck.
