AN odd note about Toyotas and fluid changes I've observed: I'm with you Jim, I keep an eye on things but I'm not so anal about fluid changes on this truck anymore because it is honestly just different then any vehicle I've ever owned.
The 2.8 GM motor's in the Trooper I drove in my youth AND the first XJ I bought both
drank about 2 quarts in 5k so it litteraly had an oil change slowly between every major change at 5k. They were both identical in their opperation, lack of power and oil consumption. I guess it's saying something that they were all that consistant as this is a fairly common com plaint about these motors. They all felt IMENSELY better after an oil change.
ALL of my VW's (high-perf Water cooled:1.6 euro HP's, 1.8's, 2.0's, 1.8T's etc) got regualr changes at 3K just because I was really hard on those motors being that they saw track time along with me driving them like a total ************... What's funny is that THEY all felt like they got alot smoother, ran better and I dare say addded a few horses under the hood every time I changed the oil. All of them, I'd change the oil and then marvel at how quiet the valve-train was and how smooth even the 1.8 8V N/A motor pulled and revved.
All my 4.0L's were the same. Change the oil and it feels like the truck wants to run better, smoother, cooler etc. I almost got into the habbit of changing fluids TOO
quickly because I loved how much better the motors felt and I rationalized that the motors were lasting longer if I gave them this kind of treatment...
The Toyota is completely different. I use good Toyota brand oil filters on her now after what I consider a fluke failure of a case on a Fram filter theat left me on the side of the hwy. for a hour or so untill I got my Dad to bring me some tools and an extra set of hands to get he old one off and the new one on and refill the motor. BUT, this little 22RE (and the one it replaced) feel exactly the same weather they're freshly changed or they're pushing 6K on a filter/fluid change. I notice they're finnicky about having coolant in them and like to rev-up if you're low, but they run smooth regardless of oil change status and really when I change at 5K the oil is in such good shape I can't belive it's been in a motor for that many miles. It's so good we have a seperate sump that we keep to use as oil around my dad's shop for little things here and there. It really is the first motor I'vve ever owned that's like this. In australia the one gasser Hilux we had was the same. The truck was completely falling off the frame, but the 22RE just chugged along smooth and for a 22re fairly quiet.
Something that DID take me a minute to get used to was the "22RE" noise that in one of my VW's would have sent me home thinking I had a stuck valve... I realize you ahve a far different engine, but something in Toyotas engineering and manufacturing practices makes motors and what not last and run well for long time intervals. THey had a few hickups in their reputation (the 3.0 V6 comes to mind and even it's not the WORST motor, that title belongs to the 2.8GM motor... WOrst motor ever made, I hate you GM for that motor!!!!!) but in reality they can really make a motor last and run smooth. They may be a little rackety at the top end, but boy do I marvel at the engineering that goes into these trucks (and car for that motter). Supras are a good example, they'ew pretty easy to wring 500hp out of and 1000hp has been done and was still apparently somewhat drivable (I think that's relative though and I don't really buy that). 500hp being do-able on stock internals.
Just something that rang true to me about Jim;s post and oil changes in HIS Toyota sorry for the hijack
...Anyway, back to your
great truck Jim, I love those Tundras and I'm glad to see you loving yours so much. Someone already beat me to saying this, but it's awesome to see how little you really need to do to make one of these trucks into a great camping/exploring platform. Some tires and maybe some armor and away you go. That's the exact truck I'm trying to get my dad to relace his aging and struggling 98 XJ with to tow his Kubota and dump trailer back and forth from the coast cabin to thiser house here in Portland.
Question about your truck bed Tent: Do you find that it does well to keep the floor dry??? What I mean is do you have issues with the bed collecting water and then having it leak into the tent or does it cover the bed sides in a way so that the bed stay's dry???
Cheers
