ARAMP1's Ultimate TowRig Build Thread


Well, since nowadays you’re not cool unless you have a build thread, I figured I should do a build thread on my tow rig “Big White”. :pimp:

SUBJECT: :crewcab:
Big White, as my truck is affectionately called, is a 1990 Chevrolet V3500 crew cab dually. It’s a Silverado model, so it’s fairly high on the options. And, I bought it in late 2005 with only a bit over 60K miles. All in all it’s a good starting point for any project.

I’ve been looking for one of these trucks (crew cab, 4wd, dually) no kidding since 1996. I got married to my first wife in 1997 and she was totally against getting "one of those old trucks" or really any vehicle older than 3 or 4 years old (even though she enjoyed riding around in my 68 GTO convertible). I continued to look until we got divorced in 2003.
In 2003, a buddy and I drove from Sumter, SC to north of Boston (over 14 hours) to look at a truck. I turned it down due to the excessive amount of rust and drove 14 hours back home empty handed. Here's a pic of that piece...

During my search, I've looked at a bunch of these trucks. As those of you who have looked for a crew cab, 4wd, dually know, they're fairly hard to come by. And, even harder to come by are the ones that weren't used and abused as a work truck during it's life. I've kept this picture of one that I looked at in Missouri and seriously considered purchasing around 2001 or 2002. This one was beat to hell and he wanted around $4K if memory serves me right.

In 2005, as I finished pilot training, I came across “Big White”. My fiancé knew I’ve been looking for one of these trucks for a long while. I even came across an old truck trader from 2001 that I bought to inquire about one of these trucks when cleaning out the house. She told me right then and there that I needed to get “Big White”! I still have that old truck trader...(see the top right 91 GMC? It's a four speed too. They wanted $16K back in 2001!)

Make this truck into the ultimate towrig. What does that mean? I’m not sure. I think “ultimate towrig” is in the eye of the beholder. The modifications that I’m planning will increase capability exponentially; however will take away what little practicality this truck had to begin with. Excess is the American way after all. :cool:

Engine: Detroit Diesel 4-71 supercharged, turbocharged and intercooled (all Detroit 2 strokes are supercharged)
Transmission: Roadranger RTO-9513 13 speed overdrive
Transfer Case: Divorced mounted NP205
Aux Transmission: Brownie/Spicer 5831 with 2:1 underdrive/0.73 overdrive
Front Axle: Dana 80, late model Ford metric hubs with 4 piston calipers/disks, 10 lug, some kind of locker (possibly ARB)
Rear Axle: Dana 135, late model Ford metric hubs with 4 piston calipers/disks, 10 lug, some kind of locker (possibly Detroit Locker)
Interior: Custom semi style dash, Vintage Air A/C, late model F150 leather seats, sound deadening
...and a bunch of other stuff/ideas that have been floating around in my head.

I’m currently in the “gathering parts stage”. I’m deploying shortly and will have to put a hold on the project for a few months until I return, but I’ve got parts of an engine and transmission.

Why a Detroit, you ask? :dunno:
I've thought about doing a 6.5L turbo, a Cummins, a Duramax, and even some others that I'd be laughed at for mentioning. The 4-71 will definitely be different.
Listen to this!

It’s the smaller 4-53 too.
