Just for anyone who may have some of the same questions concerning the Rig Master APU that I had everyone here was very helpful. I took my truck to the Speedco in Hammond LA and they serviced my truck and Apu and the service there is great they are very nice people and I highly recommend them I will be going back again.Thanks to Fatboy for the info about the Speedco in Kansas. I only wish they could change the belts but thats ok. Be safe guys and gals!
