After driving up to Alaska and back once again in 2015 towing the same weight as before and now having the Banks Power Pack installed, I was VERY impressed with the additional HP I had for climbing grades and accelerating on freeway entry ramps.
Plus the unexpected surprise was getting a full 1 MPG increase if fuel mileage.
For those owners that have a dead Ottomind Controller, I have also found a possible source that may be able to repair it.
Their name is Chuck's Speed and RV Center
in Phoenix AZ.
