I wrote you a year ago about a repower project I am doing. I have a 28ft airstream motorhome and I want to diesel it. My goal is to have plenty of power and get some where between 14 and 17 mpg. I have a friend who has done a similar transplant and is getting this kind of mileage. My coach only weighs 12000 lbs. The motor I have purchased is 93 230 cummins with an allison 3060 tec11. The engine seems to be a good choice, but the trans is huge. I could save 300 lbs. with a 1000. Can a 1000 be mated to a mechanical cummins? Would the 3060 cost me milage over the 1000. Another question that is haunting me is, will the severe downshift of the 3060 be to harsh for such a light coach. Do you have any other Ideas for what trans I should choose?
