Thursday morning we found ourselves in need of service for our CAT engine and Allison tranny. Call CoachNet and they put us in touch with Interstate Power System in Sioux Falls SD. Their return call was within 30 minutes. They called Interstate to confirm they work on both Cat and Allison. We then called Interstate and they would see us as soon as we arrived. We received wonderful service from both. It is Wednesday and we will be on the road. Interstate employees are professional. They were immediately able to diagnose the problem and get the correct parts ordered and installed with a minimum of down time for us. Highly recommend both services.
