That would mean I would get to spend about 11-12K more on my Dodge
I didn't think I would ever like a Dodge truck this much, but its hard to beat a truck that comes with a Cummins, granny 5spd, all gear np205 transfer case, Dana 70 rear with a powr-lok, and a dana 60 front all from the factory. Sure, I could change a lot of things for a stronger and more powerful truck, but what do you really need anyways.
To meet the requirements for this little exercise I would....
-Change around the rear storage/sleeping system to use two cots that rolled up against the sides when not in use and allow easy access to the gear stored below. I would use cheap plastic storage containers from walmart with a decent tie down system. This would keep everything in the back pretty organized without costing a fortune.
-Build front and rear bumpers. Something simple, clean and fairly light.
-I would buy an affordable winch, something like a xrc10 smitybilt and install it on a multi-mount system to pull on the front or back. More importantly the winch could be stored in the back locked to the floor and hidden out of sight.
-Do some body work and paint the truck so I don't look like a midnight drug runner. Some Rustoleum would be fine as long as it was one color and reasonably smooth
-I would rip out the front seats and replace them with something comfortable. Some lower end suspension style seats would be more than enough.
-I would also mount a small fridge between the two front seats to act like a center console and provide icy cool beverages and some cold food storage.
I am sure I could think of more....but I would feel comfortable taking the truck on a trip like that generally like it is.
Start strong, build light, and keep it simple.
