Jeep Cherokee Forum - Oregon to Texas in a 200K mile 99

I'm getting ready to take this 99 Limited AW4/242 from Portland, Oregon to Austin, Texas. This will be the 4th vehicle with over 200K miles that I've driven across the country.

In the last 2 months, I've gone through this Jeep and replaced/fixed a lot of things.

All new(Up Country)shocks, leafs, coils, LCAs, track bar and sway bushings
235x15 Cooper AT3 tires
Full Tune-up
4 Hole 784 Injectors
All new exhaust including Manifold, o2 sensors and muffler
New U-Joints up front with new Timken Wheel Bearings.
Valve Cover, Distributor, Rear Main, Oil Filter Adapter and oil pan gasket
Cooling system flushed + New Thermostat. I didn't replace water pump because I am lazy.
Brake flush, transfer case fluid change and power steering fluid change

I thought about installing a trans cooler, but mine came with the external one and I don't feel like replacing it since it's not leaking

I plan to carry coolant, oil, trans fluid, brake cleaner and a big tool bag of all common Jeep tools. I'm also carrying a lower radiator hose, water pump, thermostat and a tire patch kit.

If anyone has other suggestions for what to bring specifically for the Jeep, please let me know. I'm hoping to get 17MPG highway at minimum
