I have to concur with Mike Q. I have a Toyota pickup (22RE) with 310,000 miles that doesn't burn any oil and runs perfectly. You cannot kill these trucks. For a bug out vehicle (BOV) you can't beat these trucks. - Larry
I have owned two Toyota trucks since 1995. I thought I would share some knowledge I have gained on Toyota truck platform with your readers if any are interested in owning a Toyota truck.
First, the most reliable and maintenance free Toyota truck model is the 1989-1995 22 RE 4-cylinder engine with five speed (manual) transmission. This is a fuel injected engine. If maintained well, 500,000 miles on the engine is very possible. I recommend adjusting the valves on this engine with a feeler gauge every 20,000 miles. The no.4 exhaust valve is prone to "tightening up" due to heat. This can be done by the amateur who is "willing to pay attention to detail' but a good mechanic is recommended. I know many owners of this model of truck who never have adjusted the valves, so it may be optional, I'm just a stickler for performance.
The base model for this truck weighs only 2,700 pounds, and has gets 25 miles a gallon at 55 miles per hour on flatland. (Yes, 25 miles to a gallon if you are careful.) The transmission can be used to downshift almost to at least 10 MPH without brakes if engine RPMs are watched, and the parking brake can be applied to bring truck to a dead stop.
The 4-wheel drive version is almost impossible to get to get stuck if care is taken, and due to its light weight, being "pulled" or "winched out" of a bad spot is easy.
One other quark of this truck is access to the fuel filter. I recommend pulling the passenger side front wheel off to get easy access to the fuel filter behind a plastic flap.
The truck I had was the most "Caveman" of the modern trucks. I only had an air conditioner and heater, no powerlocks, no modern computer screens or other electronic garbage. This truck is fuel injected and unfortunately I do not think it can survive a EMP attack or solar storm.
On parts availability, millions of these little trucks were imported, some parts of the country are saturated with these trucks, some are not. Parts are found at (or ordered easily) at most major parts stores or from the dealer at a premium. Used trucks are selling in my state for $2000 to $5000 each depending on condition. In a collapse, I think the fuel would run out before parts would get wore out.
A word of Warning to most would be owners on this truck, this truck is so lightweight that it bounces around on rough roads and at speed you may "hit your head on the headliner' when you bounce around on the bench seat. So wear your seatbelt!
Cleaning is easy, on the rubber floor of the truck, there are two rubber "grommets" that can be taken off and a hosing out the floor of the truck is possible, just avoid the dashboard, fuse box etc. (I have even hosed down the bench seat) The dirty water will drain right out of the cab of the truck through the grommets (remember to replace the grommets, if your drive through a creek, you may live to regret it)
I had the same truck for 12 and half years, now I drive a newer (2002) Toyota truck with the six-cylinder engine. My mechanic has the exact same truck, with the same six cylinder engine and transmission and his truck has 527,000 miles on it and he still drives it everyday!
On the six cylinder engine: Replace the timing belt every 90,000 miles.
This 527,000 mile engine has never been rebuilt, the heads have never been off and the same automatic transmission has never been rebuilt! (this 527,000 mile Toyota truck has had five timing belts replaced)
As per JWR's recommendations I would not own any vehicle newer than 2002 due to [their profusion of] electronics. Some of the newer models may be okay, however, I like old things that are not so full of electronics.
The 2002 Toyota truck I currently own should last at least 20-25 years with proper maintenance. I'm 45 years old, so this may be one of the third to the last or second to the last vehicle I own in my lifetime. Regards, - E.M.
