John has an 02 and you will find most guys are running the ET over the cleaver 100/1. An ET is a no brainer for your rig. Hoss makes a nice prop also. But for your first experiance with props on an Allison just get an ET and be done with it for a while.:big grin You can find almost new ET,s fairly simple. Once youve got things down with the driving as you go you will try other props you will like but just to keep it simple the tried and true ET would be a good place to start. Like John R always says you cant try to many props.
Welcome to Da Family.:big grin
