Interesting summary @WilliamA! Thank you. So, does "resetting the computer" by disconnecting the battery, cause it to relearn from the beginning, or does it retain its 'blocks'? Would that help it to learn the 'trailer towing' block more quickly?
Also, with my manual transmission, does higher RPM (for example climbing a hill while towing) cause more (or less) overall stress or wear, as long as the temperature gauge is normal?
My theory has always been that 4500RPM is fine, for example if the red line is at 5200.
It's been some time since I did any troubleshooting of this detail so my opinion may be a bit dated by rapid advances but the theory is pretty much unchanged. That said, when you disconnect the battery, it should do a couple of things: first, it will erase the stored trouble codes. Second, it should reset most parameters to "factory" preset values. That provides a valuable tool for technicians (switched from "mechanics" for now obvious reasons) to see if the trouble code immediately repeats, pointing to the suspect fault. It gets muddy here because some codes are triggered by component failure and sometimes by parameter. For example, the dreaded O2 sensor my be a mechanical problem with the sensor itself. Other times, the sensor may be mechanically sound but reading a condition in the exhaust that is out of bounds from what the computer expects to see as a minimum or maximum. Often, the condition causing sensor failure failure will in time destroy the sensor, leading to not one but two problems: out of range condition AND sensor failure! In that case, replacing the sensor without troubleshooting and mitigating the cause will just lead to another sensor failure. The technicians' bane is that these things can quickly escalate into stupifyingly complex problems with multiple root causes. This is often made worse because neither the shop nor customer wants to pay for seemingly unrelated diagnostic time leading to vehicles going out the door with no codes, but the original gremlin still happily in residence under the hood. Seemingly unrelated issues raise havoc with everything and ultimate causes may appear (if they appear at all!) only by thorough examination of.....well.....everything. Overheating may turn out to be a transmission issue. O2 sensor failure may ultimately be caused by the fuel pump or pressure regulator. As a side note, it's my humble opinion that the worst thing you can do as a user is to try and eliminate your own problem by wiping the memory, ie, disconnecting the battery. This seldom (never?) fixes the problem and erases the computers' record of parameters leading up to the failure. It's the same action as having the maid clean the room at a crime scene, THEN calling in the investigator. The computer memory overwrites itself in an endless loop, but there will certainly be valuable information stored so long as its not erased before diagnosis occurs. The technician will certainly erase the memory, but he'll download the history first. Things seldom happen in a vacuum (sic) and GM, or Ford, or whoever, engineers will want that fault file. If you erase it, it's almost guaranteed that the first thing you've accomplished is added diagnostic time onto your bill. As a driveability technician, the thing I dreaded most to hear from my mech-savvy customers was: "she threw a code, so I erased it to see if it would come back". Grrrrrrrrr....Ka-ching! Technician makes a mental note to add 3 hours to the estimate.... In industry parlance, these are called "driveability" problems. That's the guy in the shop with the computer workstation in his bay with the Deerhunter cap and pipe, sifting data in an effort to root out the head gremlin. These guys are often found reading manuals at night and on days off, monitoring the internet for trends and tips. They work hard because the system demands it. It's difficult, challenging, occasionally rewarding and constantly changing. I've been that guy and am still bothered 15 years later by "the one that got away". Speaking to the point of the thread as I suspect I should, the plugged catalytic converter problem is a widely known issue and speaking only for myself, I'd have looked there early in the diagnostic chain. Many factors weigh on overlooking the obvious and any tech worth his/her weight in axle grease would publicly commiserate and privately wipe brow and thank the grand technician that "it wasn't me". Faults happen and good people have bad days. I can site examples of great techs missing simple things, like a friend who replaced 5 transfer cases in Bronco II's under a Ford recall and not putting oil in ANY of them. This stuff happens. Patience and understanding may be difficult commodities to distribute, particularly if you're the one writing the check. But I promise you one thing: technicians sweat blood over this kind of thing, every day... And 15 years later, we lay awake thinking about them.
So.... Shifting and RPM's: I don't (won't) give advice on that save to tell you how I do it. My T@G trailer and Jeep Wrangler go down the road....any road...dirt, goat trail, superslab, like I would drive a horse pulling a buggy. I let "Ole Hurricane" have her reins and determine how hard to run. If you pay attention to the car, it will tell you where it's comfortable. The term "redline" refers to the point within an engine beyond which parts will begin to exit their environs (quickly) and have nothing whatever to do with efficiency. I try to remember that if the engine is screaming, so is everything behind it. If Hurricane wants to downshift 2 gears and loaf up the hill, I let her. She'll tell me where she's comfortable. That's (mostly) what the right lane is for.

@jgram2, picnic tables were placed that way by the property owners to block access to most of the sites, which have no service. I am presuming people also 4-wheel or snowmobile through the place if they get the opportunity. Tables would hardly fend off that sheep, the goats would use them as playtoys and the horse would totally ignore them, based on some of the behaviors we've observed.
Walmarts in Sydney, Ogallala and Kearney are good. Grand Island and North Platte work in a pinch, not my favorite, though. They will all have truck noise due to the proximity to I-80.

Everyone - the sun is up, there's not a cloud in the sky, and I am usually the one who tries to prolong the adventure we are having just a little longer. But as we prepare to depart Omaha, and Nebraska proper, I can't wait to be home. We understand the area of the country we are traveling towards has been under siege by a winter storm. We don't care. Born Michiganians, we can handle that. It seems we missed the fall. Next week the holidays will be in full swing. I'm beginning to feel the effects of our "extended stay" in Evanston. Seems like we are missing a big chunk of the seasons passing. Thanks so much for the well wishes.
While pining to be home, away from the gaze of that sheep, I promise to heed some of the greatest advice ever given to me, and to "never drive faster than your angel can fly".
@dragonsdofly, my saying was upgraded by my Dad after he taught me how to drive "Never drive faster than the whole darn choir of angels up there can fly". Sometimes, it takes a choir!!

Made it to Princeton, Illinois tonight. Staying in another Walmart parking lot. Thank you, Walmart. Snow expected tonight and through the day as we make the final segment of the trip home.
Thanks for all of the assistance, advice and encouragement we have received from everyone.
We will never forget what all of you have done for us.
Especially important at this time is for everyone to know that although this upcoming leg of the journey may be treacherous, we plan to keep 2 wheels on the ground at all times. It's part of our personal safety rules. Front 2, back 2, left 2, right 2 or any diagonal 2 will do.
The journey has ended, but the saga continues.........
Until the truck is truly repaired, the bills and debts are paid, this is still the never ending adventure. Thank you everyone! May your upcoming holiday be blessed -Jim & Denise
I understand about the bills and on-going fixing of an ailing vehicle. I'm facing something similar (non-vehicle related) and the painful decision on which direction I need to go. As my Dad always told me "nothing is ever easy" (he was referring to fixing stuff at the time, but it applies to a lot more!).

A friend of mine once said everything in life is one of three things. A little give and take, a lot of moving stuff around, and a constant battle with machinery. Sounds like you had it all. . Glad you made it home, I'm sure you'll have a great story to tell once the bad stuff fades.
Congratulations!🎉 I bet a long hot shower and your own bed never felt better! ❤️ I’m glad you’re home safely and the rest will work out somehow. (It always does..,😊)
Hey @Ratkity! I’m thinking that they also just earned their “Campfire Story of the Year badge from Tab University. 😁
