Part was in stock!
This is the second time I’ve had to replace this part. Luckily for me Alberta Coach and chassis had it in stock! We travel full time and are from the states so it would have been difficult to have it delivered on our schedule. I knew I could replace it myself so all I needed was the part. It was a 4 hour round trip to get it but was well worth it to keep us on the road. The people at ACC were friendly and professional. I would highly recommend them for all your parts needs.
