If still trying to decide how much "JEEPNESS" you want, (sorry made it up) maybe look around check with some local Jeepers clubs see if someone would be willing to take you off-road or trail ride?
Another new member asked a similar question, basically Sport or Rubi, and while a Rubi is great, and has all the geehaws to make anyone smile, and will probably never leave you in a position you can not get out of----depending on where you go, especially if you have a winch,----- for me and my "off-roading" with other Jeepers, I have yet to drive into a situation that I couldn't drive away from...without a winch or help from another Jeeper. I carefully pick my lines, and don't push the envelope as I don't want to fix broken parts.
What I am saying is stock out of the box, a Jeep will flat "outperform" most other 4wd vehicles. SO if it is mild off -roading with fairly decent trails, and access to camping/ ability to pull a trailer..you may be fine with a JKU Sport...I suggest the JKU or 4dr for the towing option...longer wheelbase. Sport or Rubi is a personal choice that you need to make based on your wants/ lifestyle/ needs/ and wallet.
The GPS thing in my mind is a no brainer----get a hand held or dash mount ......than can use it hiking/ hunting/ or fishing as well.
