Gear Vendors overdrive

I think I could benefit greatly from a GV OD in my '02 Cummins 2500 quad cab long bed. when going up a steep grade, the 3 to 4 shift really sucks *** and lugs the truck down. same for when the TC lockup occurs. I think it would be really beneficial to be able to split the 2-3 and 3-4 gears esp. while towing...I think Del has one, doesn't he? (67dart273)

So I have a buddy who has a 4x4 business and he has been doing drivelines for a long time, I ran this GV stuff by him and ask what he though, He told me to stay away from stuff like this and his reason is if the company ever goes out of business you are screwed for parts...
