XL is a basic model. no power options.
XLT has the power option available but doesnt always have it.
the "Sport/Edge" is usually a good choice for an offroader for it comes with the "offroad" suspension and vinal floors.
a ranger with "offroad" means it is 4wd and has the "offroad pkg."(skid plates, ect....)
i would say to keep your expense low you should get a 2wd and save on gas and insurance . but invest in a good winch.
hope this helps.
