Welcome to AJOR!
Suggest you look at the limited or overland versions. The interior is of much better quality and you will get the awesome quadra drive ii (electronic limited slip diffs front and rear and the NV245 transfer case) if you are going to really go offroad.
The hemi 5.7l is an awesome motor and uses about as much fuel as the 6 cyl. The 3.0 diesel is great as well, but if it goes wrong it will go really wrong.
There are a few WG and WH's for sale on here, I have a hemi one i will sell you for 11k
This really belongs in the WH section of the forum though, this section is more for introducing yourself.
