Hi. My wife and I are working August and September at Tower Falls in YNP for DNC. We already know plenty about the park; we live in Montana and have hiked and skied Yellowstone for 25 years. But we're new to RV living. We've bought a used 22-foot trailer this winter for us and our two cats, but we haven't even had it out yet. I'm hoping for some advice from veterans: What one (or two, or three) things do you wish someone had told you before your first summer working and living in an RV? Thanks.
