But splitters aren't that big. I know its not 10 speeds, but 8 is sure alot better than 4.

I have to agree with this...while having a medium-duty truck transmission would be simpler to shift than having a gear splitter (particularly a Brownie) and would certainly be cool, you're talking about quite a bit of extra weight...which will in turn reduce your payload and most likely your fuel economy as well. Also IIRC many medium-duty truck transmissions have considerably more rotating mass, which will have a negative effect on how much power you're getting to the wheels.I will agree that you will gain milage on the principal of more gears means more peak power/milage.
But if you are going to be hauling around an extra 1000 pounds of weight, and some are inexpirenced of a non syncro-ed truck trans....you can do a lot of damage if you aren't careful.
You don't quite understand how a diesel works yet. They have a VERY limited RPM range where they are truely effective, below or above and power and fuel mileage go in the toilet. Sticking 5 speed boxes behind the things and trying to pull any kind of weight is a stretch. BEing able to split gears I went from a max of 11.5 mpg towing to 13.1 , and with the added benefit of running in 4 over I don't constantly have to shift on the interstate, I can just sing along at a steady boost rate, and my empty mileage has gone from a best of 14 mpg up to the 18.5-20 mpg range. All an auxiliary box or a 10 speed does is allow you to operate the engine where it was designed to be run.
I do not understand the need for 10 speeds in a pickup. 5- or 6 is enough. If you need more gear than that you are towing to much. Big trucks use them because they haul 80,000. As someone stated earlier, you drive a big truck like a 3 or 4 speed empty. So in a pick up it is just unnessary. On top of the trans weighing close to 1000lbs and being almost twice the size
You are towing to much????? tell this to the ranchers around my hometown that spend thier lives pulling hay, livestock, and lord knows what else day in and day out. these trucks were made to work so why not work em. Ive never hooked anything horribly heavy to mine because i have not installed my suspension helpers and overloads,................It is just the simplicity and ability to be able to do anything with one vehicle and like i said before having the best of both worlds that makes this idea so appealing.
Not trying to get into a fight, and I'm actually one of those who's rather strict about not overloading a truck unless it's absolutely necessary, but I do have a few things to say about that.Well, when are you guys are going to install air brakes? All these modifications to go go go, and all of you will admit the braking system on these trucks is terrible. Sounds like hydro-boost saves your leg muscles but that's about it.
Hit the scrap yards, a couple weeks ago I saw a 80's IH day cab (looked like a yard truck) with a 10 speed and a 6.9L IDI in the scrap yard. the tranny really wasn't that big, only 3 or 4 inches longer and about the same width and height as my E4OD.

I know it's a ego boost to say "I pull 15000 lbs with my pickup" but no one will admit it's a very careful ride with no room for error when pulling that much weight. Pull the same weight with a medium duty truck and you do have more control when someone happens to pull out in front of you in an intersection. Yes I did it once because I had the attitude "I have a diesel and can pull anything", but I will never do it again.
Ok, reality session is over, back to the enthusiast bench towing session. Yes I am attacking all of you
I bloody well hope they're standard size bearings and seals! If they're not, I could find myself in big trouble in short order.I wonder if those US Gear or DNE boxes use standard sized bearings and seals and other wear parts or if they're special.
