Has anyone had any knowledge of the under/over that hook's to the back of the transmission.

The under/over I was referring to bolt's up to the back of your automatic transmission and split's your gear's.
It is offered by Gear Vender at www.performancetruckandrv.com/gear.htm

I've heard good things about the Klune Extreme Underdrive system, i don't know how hard the install is though, probably need a shorter driveshaft.

I just looked at the Klune web site and it look's like the under/over that they have is for hill climbing atlow speed's.
The one that I was looking at was from Gear Vender. I was interested in this for pulling a fifth wheel behind a pick-up.
The one that Gear Vender has will fit a 1/2 ton up to a R.V.
