Just wanted to send a follow-up note now that it's been over a year since I had the Banks PowerPack/iQ installed on my 2004 motorhome with the ISB 5.9L/Allison 2000 engine/transmission as well as the Banks Billet Torque Converter. I couldn't be happier with the performance of my motorhome. We just returned from a 2000 mile vacation trip and another trip to southern California in which we traveled with my sister and her husband who also own a motorhome but with the larger ISC/3000 engine/transmission combination. On previous trips, before the Banks equipment was installed, I could not keep up with them when climbing steep hills and to my amazement I can now actually gain on them while climbing those same grades! I would also stress when coming into West Los Angeles before the Banks gear was installed because I couldn't keep up with traffic and merging was painful when you are the slowest vehicle. I no longer have that problem and can keep up with traffic - much safer too! My transmission never heats up over 200° even in 101° weather and I do feel I have more control when using the exhaust brake due to the new torque converter. I'm very happy I made the investment! I don't normally send this type of note but I am really satisfied with my motorhome's performance! Thanks again for your assistance with the initial purchase. Best regards, Bob W. Brentwood, CA
