Hey Folks - Hope ya'll can help me out. Long time lurker, occasional post'er (looking to change that!)
Posted this on another site, got no love...coming to the experts now.
Warning - Long post...hopefully this will provide the background for the best advice.
Please comment on the Maintenance List (indicate yes/no
or add more items). Help me make this jeep run for another 75k...
Jeep Usage & Description
Driving & Usage Style - Assertive/Sensible, Do not hold back on speed, revs, weight, etc. The vehicle will be modded for me/my family (not for resale). It gets used like a Jeep and overloaded like a pickup.
Trip profile: Mostly soft roads & requisite hwy travel. Moderate off-road (some rocks, some mud) places youd go solo w/o a winch and not be the a**hole on the evening news who is 'lost & dead in the wilderness'
Towing & Utility:
(1) Single axle dump trailer (house remodel) with 2-3x/month it loaded to 4k. 1x/month 5-7k. Have Pics, will post if requested
(2) Will start towing a 1500# jeep expo trailer for camping purposes. Have the trailer already, Expo Build to start soon.
Routinely make HD runs for building supplies in jeep or in dump trailer.
Current mileage is ~105k w/ ~50k of highway/travel miles.
Lots of interior mods nets, seat covers, HAM radios, GPS, lighting, interior rack, subwoofer relocated etc
Jeep is mostly stock; JKU Rubicon Manual 4.10s. 285/70/17 Duratracs with 70% life. No lift yet.
Engine Condition typical 3.8 valve noise; idle a little rough (indicative of needing a tuneup); occasional stumble at idle; Some oil seepage around oil pan spacer no other leaks indicated
Oil 5W30 every 4-8k, depending on driving conditions (using M1 synthetic going to switch to PP Synth)
Oil Consumption ฝ qt every 3k miles with M1 Synthetic (can be higher with lots of high, hard revs); ฝ qt every 5k miles with Synth Blend

Our last trip:
we just completed an 11k mile 7 week trip with my wife, a 90# St Bernard Mix...and my new baby (now 4 months old). Overall the jeep did really well, except for the lack of power, crappy OEM suspension, pathetic windshield defroster coverage. We started in San Francisco and went to Maine, then dropped down to Georgia...and then back to San Francisco. We hit every major storm the US experienced from mid-December through Feb 1st -> and hit most of the major parks along the route (Arches, Bryce Canyon, etc). Working on a trip report...
We were ~160# over GVWR, with a total weight of 5660# with all passengers and associated road trip gear (this was a hotel/motel trip and we packed light). The jeep is stock except for an interior rack and other small items. (Pretty unreal we were over capacity)...so the stock suspension needs to be upgraded.
