There's a lot of beers to choose from. Last time I checked Portland was the microbrew capital of the world?
I think my favorite local beer would be Rogue Irish Lager.
Clarification: I see TRD OR has A-TRAC instead of TRAC that is incorporated into the eLock rear diff? I ask this because of your comment about "Lockers are better than ATRAC"
-ATRAC comes on TRD OR, TRAC is on the other trim levels. ATRAC works on all 4 wheels, a locker can be engaged while ATRAC is on.
-the rear locker on the TRD OR is engaged via an electronic switch. After that, it's all mechanical parts that, as said, force the tires to move at the same speed no matter what. The drawback is that on cornering, it's desirable to have the outside wheel moving at a speed quicker than the inside wheel (if you draw it on paper, you can see the outside wheel has a lot more area to cover during a turn). Also it can make things harder to steer. ATRAC is more of a system with computer logic to determine how best to distribute power. It does a good job doing what it does, but the drawback is that it pulses and the computer requires feedback to determine what to do.
I found DavidK's big ATRAC bible
, which is a pretty good read.
Anyway, here's some videos that should give some good examples:
In this first one, ignore that the driver has a rear locker. What I want you to focus on is the front axle, specifically the tire in the air at 00:25. This is a good example of how even though he has 4WD, he has an open front differential. The tire in the air is his 'powered' tire, which can't transfer power to the tire on the ground since there is no resistance.
Here is an example of ATRAC being helpful. Notice how the front wheel pulses
Here's an example of ATRAC being bad, specifically at 00:13.
Here's an example of a rear locker. Notice the smooth wheel movement as both rear wheels move at the same speed
I didn't have a 'bad' example of using a locker, but as I mentioned, turning can be hindered.
I'm reading up on the SR5 do my own upgrade concept that you mention. My ADD is kicking in trying to see what you get/don't get. I'm seeing the shocks and eLock along with HAC and DAC, engine skid plate, front tow hook and 114v power point....oh yeah, most importantly the TRD graphics.
this difference in cost seems to be about $1845 according to the build your own Tacoma. Is there a cost savings doing this on my own?
I am certainly capable of doing my own mods.
SR5 doesn't have ATRAC, only TRAC. TRAC will throttle engine speed, and can't be used in 4LO.
Shocks aren't a big deal, because if you are building, you will most likely lift, and when you lift, you need new shocks anyway.
I haven't had HAC/DAC so I can't comment on usefulness. I have gotten by just fine with the auto tranny, which allows me to select all 5 gears. The gear reduction is pretty good, too.
engine skid is an add-on that can be added to any package, it doesn't come included... except some of the silly fancy packages. I don't care for it, I would recommend BudBuilt or similar. On the TRD OR, you do
get a thin steel brush guard, which is good for pushing down tall grass.
Front tow hook isn't that great because it's a non-enclosed loop, which can be dangerous for recovery usage. I removed mine and sold it for $25
114v bed outlet is good for running lights and perhaps some small tools, but I haven't used it much... I keep wanting to use high amp stuff
TRD packages also come with:
-upgraded seats (I LOVE them)
-overhead compass/temp guage
-different wheels (big whoop, who cares)
Unless I'm missing something, an ARB front locker is $1,100 before labor. Talk to member all.on.black for more information, he's got it on his truck.
So all that said, I would step back and think over again how much you intend to toss at this truck and what you want it to do. If you truly want simple offroading, the TRD OR package is a great option. SR5 I would suggest if you want to truly go nuts.
PreRunner with eLock versus 4x4 with same strictly from a functional perspective.
That really isn't a bad idea at all, especially with the '90 being the trail rig. I think that would actually be a really smart idea. The new truck would have a locker and TRAC, which is going to get you through a good amount of stuff up to the point where you'd rather be driving the '90.
Based on your description of what you want to do with the '90, this new truck will easily handle the same terrain... might have some probs with sand, but that's about it?
Off a quick comparison from the web, there's a $3k difference between the TRD OR 4x4 and a TRD OR PreRunner. That 3 grand could do some significant mods to the '90:
Rock sliders $300
lift $800, maybe more?
33" tires with rims $1160
Front offroad bumper $600
Give or take some on the armor and lift, but that's just a tad over $3k.
Stupid question regarding the manually locking front hubs. Does this mean they are a "locking differential" as in both wheels move at the same speed?
No, this is different.
Locking front hubs is what you had to do on older trucks, where you would have to get out of the vehicle and turn the red knob. On new vehicles, you simply twist a knob on the dash and it engages electronically. In both cases, it is activating the 4x4, open differential, system.
The cost is not an issue, the loss of mpg is not an issue. It's more about real function to cost ratio. I'm reading and hearing that a PreRunner with eLocker rear diff is pretty capable of most sand/snow driving. This will help me decide the necessity of 4x4 of my newer truck. I say this so others don't say, "It's a personal preference" or "only you can decide that") I get all that, just want to hear from PreRunner users who take their trucks into the she'it.
Myself (and the prerunner folks) are probably the only people you will hear that will suggest a PreRunner over 4x4. There's a huge misconception that EVERYONE needs 4x4 no matter what, when simply I think it's stupid to dump money on something you will never use, or use once in the entire history of the vehicle. A prerunner with a locker and TRAC is going to do a surprising amount of stuff, especially with a decent set of tires.
