Big T,
I think you are right about there not being a brake on a transmission this size, that's why I am thying to fabricate something for it. I can't use a center driveshaft one because I will only have a one piece driveshaft (no carrier bearing) with my short wheel base, and therefore it will be moving as the suspension travels.
The RTO6613 13 speed weighs 550 pounds, it's the smallest of the roadrangers.
My truck will be a 2 ton, so still light for a roadranger, but should handle it just fine.
I don't plan to use all the gears unless I am loaded and need them, otherwise I'll skip some and 4 or 5 will probably be enough. I don't expect it to be hard to shift.
On another note, I have decided to run some taller tires than I was originally planing on. So now I don't need an overdrive transmission to cruse at 70mph. I'll use one of the RT610 10 speeds that I already have, they weigh about 350 pounds. I'll still need a parking brake.
Take a look on my picture link below to see them.
