The Limited is a nice vehicle. Every month the best bank for buck seem to change a bit. WK2jeeps.com is a good resource for all the models and option packages and invoice prices. Just pick the options you want and then compare model prices and value.
QTII is better than the base QTI if you are going to do a lot of poor weather driving and want the additional traction margin. There is no manual switch to lock the transfer case, but the QTII traction software will automatically lock it in some modes and depending on wheel spin. QTII also includes a low range capability, which locks and gives you a granny gear for off road or very severe conditions (or pulling a boat out of the water). If you want the ultimate in traction, look at QuadraDrive (only available on a V8). With proper tires, thats about as unstoppable in 10 inches of snow as you can get. The base QTI includes brake traction control, which applies brakes to spinning wheels. Works very well. QTI does not have low range, however.
Everyone has their favorite option package. I suggest looking at the adaptive cruise and cross path detection/collision avoidance (now part of the tech package I think). I'd want my spouse to have that safety, worth the extra $1500. You can lower Quadra Lift is for entry and exit (my elderly parents appreciate it) or raise it to get under and change oil. Its not useless on road and the air suspension smoothes over small bumps. If you decide you like all those features, perhaps an Overland would give you more bank for the buck, but get another opinion as I'm not all the familiar with 2014 pricing.
