I have the same vehicle; 2000 D2, Kent Green. Only difference is 7 seats. I even took the engine out to "re-seal." Haha. Well, I blew a head gasket and decided to do a "tophat" a.k.a. flanged-liner rebuild of the 4.0 engine (currently ongoing). These rigs are awesome to drive, aren't they?! Nice to see that you got a vehicle with a good service history. On the headliner, the standard headliner material is not wide enough to stretch all the way across (necessitating a special sized material). Though you may already know that. I plan to replace my sagging headliner after the engine rebuild is complete. Best wishes with camping and expeditions with your rig!
