Perfect part, delivery and service
This was a great experience! I have been searching for this part and was able to get it through this site with great ease. Ordering was easy, got a confirmation of my order and then it was there very fast! I had tried ordering a similar part from Amazon but it didn't fit. Have bookmarked this page and will be using for all of our camper needs from now on!!
