I am having trouble figuring out how to import my xPub from my Ledger Nano to a watch only Full node (Bitcoin Core 0.17.1) Could someone please explain how to do this? I am reading different things. Some people say its not possible on bitcoin core and others offer confusing explainations.
Bitocin Core does not support importing xPub but it does support importing batches of addresses. You can generate a large set of addresses from the xpub (external, change etc.) and import them with one call
You could set up an Electrum Personal Server and import the Master Public key to have a watch only wallet via Electrum and your full node.Electrum Personal Server Git Hub
