Hi,
I don't even have a dodge, so i have not a clue about specifics, but I absolutely agree with the point of "use it and see what would fit you best". If you decide you need a rock crawler then great, if you just want to do light wheeling great. I wheeled stock trucks for a long time and they did just fine, although you have to realize limitations, like don't drive over the 1.5' rock etc...
Something I have always upgraded no matter the use was tires, not even size (although bigger is usually better off road), but to a better offroad or all terrain tire. Something with the appropriate tread for what your doing, and a higher ply count. I like running minimum 8 ply and i prefer 10 ply and a 3 ply sidewall. They are a bit pricier but keep you from a lot of flats and hold up well with a light air down off road. Even stock size off road tires will make a world of difference when off road over a highway tire.
And hey, they are a wear item anyway so its only a matter of a small upgrade from stock.
Cheers,
