A few weeks ago I ran across a website of a company that converted class 8 tractors (big rigs) by cutting out one of the rear axles and shortening the length. Alas, I didn't save the website and now I need it. Anyone know the company I mean? I'm thinking they might have been Canadian but I'm not sure. Thanks.

I wonder why they would bother, class 7 tractors are plentiful.

Hi,

THere is a lot of information about converting class 8 trucks into class 7, that will give you about 400 - 425 HP engine that is normally going to get close to 8 MPG while towing any size RV fifth wheel.

And with modern transmissions, they electronically shift from one gear to another with autoshift tecnology, they are pretty easy to drive, with the tight turning radias, are easier to get around in than a 168" wheelbase crewcab truck. And torque - in the 1100 to 1350 range!

There are several words of causion. One being you want to get rid of the center axle, not the rear one. The center axle has a input and output shaft going through it, and is not suitable for being used as the rearmost axle.

The other word is the 14 liter inline 6 will overload the front axle if you don't have a substantial amount of weight on the rear axle. So pick a 12 liter engine or smaller, and if you happen to like the 14 liter, make sure it does not have the 14" setback front axle, or that the front axle weight is well within the GAWR for that axle before buying.

Also it is recommended to have the potentail truck put on a dyno, and see if it is actually still putting out 325 HP to the ground or not. A lot can be learned, and if the dyno test shows overheating or lack of power, walk away from that truck and find another.

If I converted a class 8, I would probably take off one of the 150 gallon fuel tanks, and only use one. 100 gallons at 7 MPG is plenty of range, and that extra tank is just another 1,000 pounds to carry around. (tank weight + 100 gallons or 600 pounds of fuel).

Fred.

Because they aren't big enough.
