Talked with Bob on Thursday while ordering PUG's for our new 233S. He is attaching Velcro to ours. This will be our 4th set. They work really well. He did clarify a PUG myth. He states to always leave the shiney side up. Flipping them over he says does not retain heat in the winter. I told him that's what I had been doing for 10'years because I had read it on one of the forums when we had our Fleetwood Avalon PUP. It made sense. Bob is a great guy with a great product. It's awesome to support small business that makes things in America.
Have a great night.
