Poolbug 54,
To answer one of your questions, yes, my 2019 Hathaway 34RL2 uses a 7/8" size. I have one of those lug wrenches that has 4 different sizes. Very handy.
OBTW - is that Hartwell, SC? If so, we have good friends that live on Lake Hartwell. They used to be Cedar Creek owners, but now have a Mobile Suites.
