Congrats on your new XLR and welcome to the Forums from a fellow NY'er!! Hope you have many fun, memorable, and trouble free trips with it! As for an owners manual, if it anything like the one I received with my '08 Berkshire, it could have been written by the owner of any brand of RV. It was very generic and didn't address anything specific to the unit I had. You are better off just posting any questions you have here and getting responses from the people who have dealt with the issues already.
Again, welcome and good luck with your camper!
