I am sure somone will correct me if I am wrong but I beleive all of todays automobiles are rated with all accesseries turned ON but I am not clear on if this on an engine-dynometer or a rear-wheel dynometer.
Good question!

Cyoungstrom's numbers are therefore right in there for the HP. I am a bit worried about the torque figure though, that seems awful low - the engine is rated at 295 so that would be a 49ft/lb drop. Anyone know whether rear end makes a difference to this, and if so which one was tested.
99 Silverado 5.3l Claimed HP 270 Torque 315
Measured at rear wheel HP 173.1 Torque 198.0
99 F-150 5.4l Claimed HP 260 Torque 345
Measured at rear wheel. HP 186.0 Torque 249.6
99 Ram 5.9l Claimed HP 245 Torque 335
Measured at rear wheel. HP 160.4 Torque 219.0
00 Tundra 4.7l Claimed HP 245 Torque 315
Measured at rear wheel. HP 168.1 Torque 201.5
All testing was performed on Paxton Automotive chassis dyno.
I was unaware that so much loss occurs through the driveline. Any technical folks out there offer a more detailed explanation.
Thanks......Reed

I'm not sure I like the looks of the Leer 100XQ, they tried to make it look like a Durango, with black wrapping around the front and bottom. I like the looks of a standard cap better, so that means waiting until the other manufacturers catch up I guess.
I'm thinking I'll just pick up an Extang tonneau for now and get a cap this summer when there are more choices.
Anyone have an extang? I'm trying to decide whether to get the one with snaps (classic) or the saber with the "zip-loc" style attachment. The price difference is negligible.
Also I'm waiting on the Bedrug, they say it could be up to another month before they are available.

good luck all,

I'm looking at a cap as a way to create a roof rack system to haul my kayak and canoes. Any ideas for a rack system? The truck is essentially 18 ft long and the canoe and kayak are 15 ft.
Although there are very technical reasons for this, Perhaps the easiest to understand is the fact that the automatic gets so HOT that it needs a special cooling radiator. Where do you think all of this heat comes from... IT IS POWER FROM THE ENGINE LOST AS HEAT!! (Power that never reaches the rear wheels)
A manual xmission may get warm but its 'losses' are meshing gears, oil-churn, and some bearing friction... Thats it!
In engineering, the measurement of this heat is a valid way to calculate the losses. Do you recall "Energy is neither created nor destroyed"? It is only converted to another form.
On another note; has anyone experienced any puddles of what seems to be water under the fire wall on the passenger side? I have a 4.7 automatic. Dealer tells me it is condensation from the a/c and/or heater. this doesn't sound right to me as I have never seen any other vechicle leave puddles... It is definately not oil or antifreeze.

Things have speeded up quite a bit now though, once it gets on the line you better buy up those accessories cuz you'll have it soon. :-) Good luck.
I love my truck more every day! I've even gotten used to the seat (don't feel like I'm falling off the side anymore :-)

I have the 3.55 LSD rear end and it is quite suitable. Only the people that have the 3.92 will tell you the MPG is not affected. Simple physics tells us otherwise. Do not get me wrong... For heavy towing, the 3.92 is the best choice.
I have the sales brochure right here is my hands and the 3.55 is rated up to 9,500 GCWR (Gross Combination Weight Rating) The 3.92 adds only 1,000 Lbs to that.
BTW: I was informed by 2 seperate dealers that the LSD is MANDITORY with the 4.7 5sp. Even their computer that orders the truck enforced that rule.

I have answered this several times already. Please click on <410</A>> (The LSD is mandatory with the 5sp manual.... not the multispeed Automatic)
Are we talking about puddles INSIDE the truck or soaking into the dirt in my driveway? 410My truck could leak GALLONS of stuff and I would never know it.Pickups If we are discussing water underneath the vehicle after running the AC... this is unquestionably from the evaporator core inside the vehicle which can produce copious amounts of condensation. There is a drain hose leading to underneath the vehicle.
1) I do not use the AC, and;
2) I have left the switch in the floor/vent position without ever changing it for the past 4 weeks.
Humidity is very high today, and may have been the last time I noticed it as well
Specifically which position are you referring to when you say...
I have left the switch in the floor/vent
position without ever changing it for the past 4
weeks.
Do not forget that the AC is 'enabled' in most of the selector settings. (An easy way to tell is to stand in front of your Dak while it is idling and listen for the electric fan... it will only be whirring if the AC is on.. it is quite loud)This is only for 2000 models!! (No electric fan in previous years)
By the way, I noticed that Chevy has a nice 3/16" or 1/4" thick insulating blanket wrapped around their accumulator. I recalled that after test drives in the Dakota last summer and noticed the amount of condensate dripping all over the engine compartment. Ever hear of anyone wrapping theirs to prevent excess condensate from dripping all over the frame etc?
the Jeep Grand Cherokee. The Jeep forums contain
much praise for the engine, and much bitching about the transmission.

If you are talking interstate and not smaller two lane roads, your highway trips will pose no problems at that speed (as long as the rest of traffic is moving at that speed). These trucks are quite stable at higher speeds from what I have experienced. Just give proper following distance to ensure stopping (heavy trucks = slow stop).
Chad
The Rack/Pinion steering is very nice addition on the 4X4 for 2000.
BEWARE The tires, as deleived from the factory, may NOT be suitable for these speeds. The owners manual has deatailed warnings on how to increase tire pressure for limited highway travel.
If you expect to travel at these speeds for xtended periods (hours) please consider tires that will be both SAFER and QUIETER.
I have the 31X10.5R15 which are HUGE tires rated LT (Light Truck) and I am quite aware of their speed limitations. They are designed to carry WEIGHT. The only reason I got these tires is because they come with the rear sway bar package. In retrospect, I should have just installed an aftermarket antisway bar for much less $$
Do not let anyone lead you astray... the LT tires have that rating because of the increased LOAD carring abilities by way of STIFFER SIDEWALLS. (And a harsher ride) If you do not intend to carry concrete block or other loads for extended periods... DO NOT GET LT RATED TIRES. You will be rewarded by a smoother, Quieter, better handling Dakota.
One person in these forums actually replaced the factory tires immeadiately with P (Passenger) rated tires. One can Sell or store the removed tires since they are still brand new. Perhaps a deal can be struck with the dealer to install highway-worthy tires as part of the purchace.
I guess the other way to go is with the package P235/75R15XL's on the 15x7" wheels, then buy and install the wheel flares and sway bar on your own. My only problem is paying for two sway bars.
Since I to like the look of the Tire / Handling package, want the stiffer sway bar, I'll take a chance on the tires knowing that I can get something softer / quieter later on.
Final note - Thanks to this forum and #841, I've gotten more and better information on the Dakota than offered by DC. I'm reminded of this every time I talk to a saleman and know what packages and combinations are available, common problems and how to resolve them (hopefully), better than thet do. Nothing like having a "team" on your side when you're about to spend big bucks.
Found this board a couple of weeks ago, and you were all very helpful! I finally took the plunge and ordered my 4x4 Dakota Quad Sport last weekend. I put a bid in on Priceline, but wasn't happy with it (dealer came in $461 above my bid of 3% over invoice). I declined, then called the dealer where I test drove the Quad -- he came within $120 of my bid. So, I was happy with the price. Hardest decision was the color. Couldn't decide between the Patriot Blue or Forest Green. I picked the blue -- but then was told I couldn't get it in the Patriot Blue (only SLT). So, its Forest Green for me. My question: Anyone out there got one in the Forest Green color, and can tell me how great it looks?????
