Not looking at too much offroad, planning on it being an "all roads" vehicle. No winch (too big for a normal 12v winch) but I did order a 30' x 1 1/2" kinetic tow rope for those moments. Also a few either Maxtrax or sand ladders for the soft stuff.
The 4x4 freightliner carry a big premium over the 4x2. I have been keeping an eye on the market just for information as I'm not close to buying one yet. My wife and I have traveled to remote areas like Patagonia, Chile and have rented 4x4 campers (pickup with slide in) and have only really needed once or twice. But I tend to think that with a well layed out truck with good tires we would have been ok with 4x2. I have no intention of going wheeling with a 10 ton truck either, but I want to learn from people like yourself what is needed vs what there just to look cool.

2WD with plenty of clearance, plenty of tire floatation, good turning circle and a locking diff can go a lot of places. If you find that you need a nimble 4wd to see something get a local to take you there.
Now I have finally put 1 of the tires on. They fit on the front with a little boring of the lug holes (21.5 mm to 25mm). It looks like it will just nip on the springs at full lock so a steering bumpstop massage is needed. No hope in fitting them to the back until I get the plasma out to do some redneck panel work.
Bummer is that boring out 1 wheel has cost me a battery drill. The bit got stuck in the chuck and I cannot get it out.
Yeah I know this thread is useless without pictures.

This is more for record keeping and helping those searching for Cummins oil pressure problems.
I have been having an ongoing intermittent check engine light. After getting a couple of tools to run diagnostics it came down to oil pressure low. Now my truck has a good old manual gauge so I could confirm there was nothing wrong with the oil pressure so it was just the feed that the ECM was seeing. Not a big deal I thought. New sender and check the wiring and I am all sorted. But Cummins threw a wrench into the works. It seems like the old sensor/sensor ( cummins 3408428 ) is now replaced by a switch ( 4076930 ) and a wiring harness ( 3164755 ) and it needs an ECM re flash to work. It also turns the variable reading into a set 55psi effectively creating a dummy gauge.
After being unable to purchase the old sensor I figured Cummins probably had good reason to make the change so I would take the hit I the wallet and get the dealers service guys to swap it out and reflag the ECM. Go into the service writer and he says " I can book it in. 1st opening is Monday sometime (this is Friday morning and they are a 24 hour service center) and the truck has to stay here or you lose your spot. Yeah that's not gonna happen.
Checked with Cummins and and they take booking. Wed evening 6PM and they may not get to it until Friday. Yeah not exactly ideal as we are heading to Mexico on the 27th.
Some some more google analysis I found a couple of possible alternatives. 1 was an International part number and when I checked it out it would require rewiring. The other ( Cummins 4921511 ) has been superseded a number of times ( 4326849 ) is a straight replacement and does work.
So to summarize for the inter web searches. Cummins ISB 24v
Oil pressure sender sensor 3408428 can be directly replaced with a 4921511 or 4326849 sensor directly from Cummins. At least it worked OK I my 1999 Freightliner.

Mexico somewhere. Either Copper Canyon or Baja. Depends on what the weather looks like for the guys on motorcycles who will be in a tent.
We have a start date and an end date and nothing else planned.
