Greetings y'all. Name is Brian and i'm from So-Cal. I'm headed back to the Jeep world having given 2.5 years to another brand who shall remain nameless. :D Honestly, it was a great rig, but it wasn't a jeep and was biased too heavily towards on-road use even with some extensive mods. I have had MANY jeeps in the past (CJ2a, 2 CJ5s, 92 XJ, LJ, J10 pickup, Jeepster commando, etc) but we're specifically looking at clean, low mile Jeeps (with A/C and heat) to tow behind our F150 on trips. Here's some thoughts we have:

  • We want this to be a capable rig, but do not want to move away from stock components - no plans for an Atlas or anything. Got burned using an aftermarket crawl box in our previous rig and I don't think we want to go that route in our next jeep.
  • This needs to be an all-arounder offroad, we live near dunes, rocks, wide-open desert, long single track climbs into the mtns, etc.
  • small (BFG) 35's max (but more likely 33-34's)due to storage height limits, and also mobility issues getting into a tall rig. LCOG (within reason) is a consideration for us.
  • Cost wise, it's hard to beat a 4.0L/32RH/NP231 running 4.10-4.56's dual locked on 33's-34's. Trick for me is finding something with a Dana 44 - not very common with an auto around here. Dana 35's with aftermarket 30spline axles and locker is an option, but not sure I want to put that $$$ into a Dana 35.
  • I do like the rubicon models, but
    • man, they command a premium around here ($8-10k more, easily)
    • Not a fan of the 42RLE (we had an 04 LJ)
    • While I think the NV3550 is a great unit, and i can drive stick very well, we want to rock-crawl when the opportunity arises and preferred an auto in Moab, but still chewing on this. My wife isn't opposed to a manual, and is willing to learn - just have to see what we find.
  • LJ's are cool and a good solution for some, but wheel way different than a TJ. If i decided we just need more storage and interior space, I might just pay less than half the cost and grab an XJ?
    • 4.0/AW4/231/Dana 30/C8.25 on 33's is a pretty sweet setup - no real downside drivetrain-wise.
    • Basically, same wheelbase as an LJ
    • $5-10k cherokee's are readily available around here
    • Anyone else make a similar decision? I've had both, and while the XJ is more streetable, it doesn't give up much offroad, in my recollection.

Anyways, I welcome your input - and thanks in advance for all the great information on this site.

Welcome to the forum.

What gearing did you have with the 42RLE?

Thanks! We had whatever was stock - 3.73's, I think? We kept our mods minimal. we ran 30-31" aggressive all-terrains a budget boost for an inch or two of lift, a congo cage, Sliders, diff armor, and a simple winch plate for our Warn M8000.
 
Just figure for 33's, you're going to want a 4" kit. For 35's, you'll want 4" springs + 1.25" body. So it's not much difference. Though better gas mileage the smaller you go, and less likely to break something. Just figure your tire size should determine your height and gears.

Dana 44 is going to be ideal, but I wouldn't turn down the 'right' rig with a Dana 35 if you don't mind doing a super 35 kit.

Or go with the XJ (or other Cherokee) if you can find one you like. Not the focus of this site, but you might save a significant amount of money if that will get the job done.

There may be a really well built rig on the market soon. 44s, 35s, LJ, not sure what the cost will be though.

Thanks for the guidelines, and I'll have to take a look at the Super 35 kit. And yeah, I don't think we'll end up going the XJ route - been there done that. It just pops up in my head whenever i think about LJ's again...haha. (I'll be the first to admit that i'm an overthinker. :D)

I have two: an 06 LJ on 37's for wheeling (see profile) and a near stock 04 TJ Sahara on 31's for a DD. The LJ's are getting harder to find and the prices are going up. So budget is a big consideration. Socal is a great place for wheeling. Trails for all builds.
 
That's a lot of extra weight. Did you at least have an aux. trans. cooler?

I agree, not to mention hauling our two kids at the time.

Yes, we did have one actually! Had to think on that for a second (we owned it almost new in the early 2000's) - we bought ours as a certified pre-owned and it was already installed.

Budget is $25k all-in (preferably less..lol..but that's the upper limit where the piggy bank runs dry.) That includes rig, mods and trailer/flat-tow setup (budgeting about $2500-3000 for trailer setup gets us into a new one with brakes, but it's the weight that becomes an issue and only a smaller rig would do) Flat-towing = more choices in vehicles.

I agree, we started wheeling as a family about 3-4 years ago and the On-X app has been a gamechanger - i had no idea how many trails were nearby.

If you’re hauling gear for 3-4, LJ or XJ. XJ would theoretically be superior for towing with the leaf springs if you wanted to trailer something.

I saw this LJon Autotrader a few weeks ago, may be more modified than you want. It’s in LA

Thx for the suggestions.

We only do day trips. No camping/glamping for us.

Gear needs are minimal for us (trail tools/spares/snacks/recovery gear. We’ve done several places (pismo, Missouri, Moab, anza borrego, etc) for a couple days/couple weeks out of an AirBnB house. Great to cook a meal, sleep in a bed, take a shower after a day of wheeling. Duffels/cooler(s) will ride in the F150 then get stowed in the house. If I do a solo trip to the Rubicon eventually- lots of room w/o the rear seat in a TJ, right? I should probably do some research there on how big a space it is.

I wouldn’t describe it as lots of room, but that’s subjective. You could install removable drawers, shelves, etc. depending on how much space you need.

:
First up will be a baseline maintenance. All fluids drained and refilled, all lube points hit, all hardware torqued/tightened, new serp belt, etc.

Steering is VERY smooth and tight but i do see a few rod ends that look moist so i might pull those, replace them and then keep them as trail spares. Also upper left ball joint is weeping too, so gonna swap that out similarly.

Few more
