For most people it would come down to cost, how much room it takes up as there are alot of cabs out there that are crammed with electrics when the body is off and for most a 3 speed is plenty...
Just my thoughts...

Thankyou for your thoughts on the matter.

Many things do not go from 1:1 down to scale. This is a real problem. this is why the trans is a lot larger than a scale model of a real trans would be. The gears inside are around Tamiya size. And there are a number of technical reasons why Tamiya went for that size of gears.
If you did a scale model of a real trans the gears and shafts would be tiny. It would be like watch making, it would be fragile and prone to breakage and bearing failures and the gears being so small would need to hardened steel and then ground...
OMG....if you think 1300 bucks is over the top, a minature scale gearbox with tiny hardend and ground gears would cost more than the national debt....

This monster 9 speed can be mounted further forward in the chassis with some inginuity reducing the overhang at the rear of a day cab to 1/2 inch.

Everything in engineering is a compromise, what one person will trade off another won't.....As i say it is a matter of individual taste...
