I just ordered the Service Manual for my 2006 KJ. This type of material is available for all recent Chrysler Products from the DC TECH AUTHORITY. Go to jeep.com, select owner services (top right) and the next page will display a menu of available services including owner/service manuals (near center left).
I always try to get the shop manual for any vehicle I own. I you do your own service and repairs, the manual pays for itself quickly (avoid costly mistakes). For jobs that require labor I can't or won't do, the manual gives me the information I need to keep the shop honest.
I moved several years ago and had to find new homes for manuals for a 69 roadrunner, a 76 IH Scout, a Plymouth Voyager, a 95 Dakota, etc. Owners of those vehicles were glad to get the manuals

. LOL
