I do exactly what you are talking about.
I travel all over the country driving my 80 some of the time, driving rentals some of the time.
I carry about 800 LB of tools and parts for industrial equipment and I am on job site from hot and sandy to muddy and wet to filled with snow.
I average 11.5 MPG.
I started with a truck that was minimally rusty in the MW. I threw a TON of maintenance at it because it was very poorly maintained. I drove it and worked on it for a few years as I baselined it. I have since put on over 140K miles.
I got it cheap, I love working on vehicles (It's my therapy as long as I'm not broke down somewhere), and overall it's great to drive because it's different. I get thumbs up a LOT when I'm driving. (I also get shown that I'm number one too!!!!)
Pros:
* I can get in it, turn the key, and go and not have to worry about something breaking while I'm on the road because these are very reliable.
* There are folks on this forum that if I were to break down on the road, I could get help within an hour or two from someone.
* These trucks can be limped for many miles with an issue so you can get back to civilization (steering, mechanical, brakes, some ignition stuff)
* Very little computer dependent items that will cause full disability.
* Toyota still makes most parts for the 95-97
* Heater works fantastic
* It's paid for.
* Annual maintenance costs are low.
* I get to drive slower so I can see the scenery.
Cons:
* There are those weird things that break that are not common, like an ignition barrel rod that took down the truck for a week.
* Factory power leather seats suck. I need something more, as I MUST stop every 4 hours to get out and pee, walk, try to straighten out, and get feeling back in my ass and back. Thank God it only gets 11.5 MPG.
* You need to use Toyota parts to insure the reliability that you need. There are some exceptions, but the big things are available and should be used.
* You must keep up on your maintenance: Oil changes, tires, drive train lubrication, coolant, cooling system.
* Gas mileage
* It takes longer to get everywhere.
* Heater works fantastic, even when it's 105°F.
* Cannot tow much due to low power and overheating
* Elevation and speed are inversely proportional.
* Preventive Maintenance costs are high, but only required every 100K.
* Insurance costs on these are much higher than others because of fewer imported and the "luxury vehicle" tax
A coworker of mine drives a 2008 Chevy Tahoe and his truck is infinitely more comfortable to drive. He does similar maintenance on his truck and does monthly oil changes. He's had a couple sensor failures that stopped him in his tracks, but the parts for a Chevy Tahoe are MUCH more available. He also gets about 17-18 MPG regularly, which REALLY adds up in fuel costs. He can also run 80+ MPH with no issues. If I go over 75 MPH, my oil consumption skyrockets, my gas mileage plummets, and I'll burn a quart of oil in 1000 miles or less, depending on how hard I'm pushing it. He averages 48,000 miles/year.
So, 75 MPH, I can get 14 MPG if there's no wind, but it takes me forever to get there. I can carry a lot of weight and look cool while doing it. I can go to any job site and go where I need to with no concern for getting stuck as long as I'm not being stupid.
I average 15K-20K miles per year.
That's 1304-1740 gallons of gas/year.
x $3.45/gallon = $4499 - $6003 per year just in gas.
The good news is I got 7 years and 95K miles out of my last set of GY Duratracs because on the highway they wear well and it doesn't have enough HP to smoke the tires......
After my trip last week, I need new seats. My back and ass hurt so much from two 12 hour drives from KC to San Antonio and back, than I was having trouble sleeping and walking.
Yeah, buy something newer and more comfortable unless you REALLY like older stuff.
My back-up vehicle to this truck is a 1959 Studebaker, so that tells you where my head is anyway (most will say up my ass).
