I forgot to add to my last post that I went to Charlotte RV in Port Charlotte for my install. I was their first Sumo Spring install, so there was a bit of a learning curve. I had to show them how it was done, but after a slight misstep on the first attempt, they got them on right. They have always treated me right on any repairs or warranty work and are nice people!!
If you go there, they now know how to install them
