Exactly. The straight 6-4.0/4.2 design is proven, with tons of aftermarket parts available. Just feed it fresh oil every 4 to 6k miles. I added a K&N washable air filter and 2” pipe, and get 23-25 mpg on the highway. The drive train is decent in the 90’s and early 2000’s vehicles, the bodywork is great, interior well done ... its a vehicle that, if you don’t trash it off-road, will easily do 200-250k miles before needing anything even resembling serious work.

Very similar setup here. ‘01 Wrangler with 2” lift and 32”
tires. K&N, bored the throttle body straight through and
a Dynomax exhaust that was a door prize at Camp Jeep. Close
to 200K and still does not touch a drop of oil. Mobile 1
used in motor, trans, case, and axles. I live in rural Ill. and need 4x4. My place is a wildlife preserve and my Jeep is
just as likely to be working as playing. Try pulling a down
tree out of your path with a Prius! (or just driving over it)
