As I approach 200k miles I am wondering what preventive maintenance might be prudent as I want to continue using the truck on long trips often in remote areas of Canada. Off the top of my head I can think of:

Starter Contacts
Ignition Switch
Radiator and hoses
Axles/CVs
Timing belt
Alternator
Battery

What else?
 
I carry a TPS and APPS sensor...because like your Canada trips there are times I just can't call AAA
 
If your wife runs off with the keys, your dead in the water!! Seriously, If you loose the key, there is no way to get it running without another key that matches your ECU, or so I have heard. John
 
Are these common failures?

Kind of, but it's one of those things that is relatively cheap insurance. If either one fails your truck goes into "limp" mode, around 5mph with the pedal to the floor. Mine failed after we got home from a trip to Death Valley. 72 hrs earlier and we would have been a days march from any kind of help. It was mid week in winter so not much chance of a passerby finding us. Plus the sensors are not something you would find a the local NAPA auto parts store, they usually take a couple of days to get from the dealership.

I would add some way to read CEL codes and a list of said codes. You can get the whole FSM on a thumb drive, if you carry a tablet or notebook that would be ideal.

Dan/Dan, doesn't the 98/99 have a conventional cable going to the TB? Have you ever tried driving with both of those sensors completely? If not, try it, it's not that bad. The last 1/4 of pedal travel will manually open the butterfly. You won't have full power and modulation is a little tricky, but it omits this from being a risk item in my book. It feels like you hit the stop at the bottom, but push a little harder and it will open.
 
Just thought of another one, the key switch assembly. That one is a show stopper because when it breaks the steering wheel locks, so even if you manage to hot wire the truck you can't steer it.

That's what I meant be ignition switch. Mine broke last year - according to indie mechanic the new part didn't look any stronger. He went on to say that Toyota engineering dropped the ball on allowing such a failed design and problematic repair for a vehicle that is often in remote areas of the world.

I thought Dan said his part looked stronger so maybe they have changed it since my repair.
 
What about just removing the shaft assembly in it's entirety and going push button start. Three rockers, one for accessory, one for ignition, a third momentary for start. You then could relo the anti-theft antenna to the center console pocket (by the shifter) and just drop your key in that pocket for security.

I hadn't thought of that. Do you have a part number for that?

Doesn't the TPS usually fail around 100-120k? I had mine replaced at 140k, so it should be good for awhile.
 
I don't know the part number but you can probably find by searching. It is apparently a bear to get to as there is two break off head bolts (not sure that is the correct term) to unscrew. My mechanic replaced with regular bolts so if there is a next time it won't be so bad - will take the risk on theft.

There is a thread on this problem with part #'s and explanations.

I think the bulk of the info and pictures start around page 5 and go to page 9 but don't quote me on that.

Absolutely right on this one. Hoses and belts should be a normal preventative maintenance tasks so should not fail in the field. I've got 274k on my 98 100 and the only non-maintenance issue I have ever had was with the ignition switch. The only other items I'm sure you know about - extra cans of gas and spare tires. These can be hard to come by up north. I've done the Dempster, the Denali, and the haul road. Spare tires that match your truck are literally worth their weight in gold (I think that's how they price them in places like Coldfoot and Deadhorse).
 
Water Pump. Mines had a slow leak for ages (4 years) and i've been lucky. I am overdue by 9,000kms for the big service (not that far over really) on the engine and the sticky here recommends you replace the water pump and thermostat (and other things) when you do that service.

You have 274k miles and haven't once been plagued by the starter contacts? I get maybe 90k miles out of a starter.

I drove a toyota corolla up the north slope haul road to Deadhorse in 1994, didn't do a tyre in, but had 2 spares just in case. Got some strange looks driving around up there........
