I can't help you much on your check list or what to look for on your V10, but I can tell you I just put the Banks Stinger System on my 454, and it was the best money I've spent on the MH other than the original purchase. The difference it makes on my coach is night and day. Now, I know our set ups are different, but the perrson that talked me into purchasing the Banks system for my coach has a 05 34' dual slide with the V10 and he highly recommended the system to me. Although I only went with the Stinger system which is the air intake and exhaust (no headers), I know my friend went with the full kit including the automind (excuse spelling).
Ironically, his reaction was the same as mine after the initial test drive. It was not wheelie pulling power increase, but it was that merging onto the interstate, passing a slower vehicle (new concept to me), and being to actually drive in OD, which I thought had been put on my rig as a decoration. In addition to the added performance, "I", not all, experienced an increase in gas mileage. Noticeable. However, I attribute most of that to the fact I can use the OD so the engine isn't working nearly as hard.
Others may have their opinions and everyones got a right to them, but I would say, for the investment I made in an older coach, it was definitely worth the money invested for the reduced stress. Good Luck.
