Maintenance maintenance maintenance!!! I would ensure your fluids are up to date, timing belt, water pump and Valve cover gaskets are done. Diff fluids and transfer case are good, coolant flush, if uncertain when these items were addressed prior. And maybe plugs while you do the valve gaskets. 4Wd solenoids are properly working and engaging all modes.
Depending on your tire life it’s very capable with normal tires but if the budget allows and depending on your terrain or snow driving I loved my Falken Wildpeaks AT3. They were quiet, aggressive, road smooth and were great in moderate mud, snow, and off road.
If you don’t neee the 3rd row it’s easy to remove and you get great trunk storage. If you camp and cook off grid you can add a table on the rear tailgate and some storage.
You can look into underbody protection. The factory steel one is pretty decent though.
Bilstine Shocks and Lovell shocks are a great inexpensive upgrade and will make a huge different in ride quality. Don’t forget to look at away bar and links, control arm bushing or tie rods.
The parts for these trucks are reasonably priced yet you don’t need to change or fully build this thing out to have fun with it and get off grid.
