Buy good sewer hoses....I have the Rhino ones. They last and I have not had a pinhole leak or anything like that at all. Get some good comfy outdoor chairs. We have a "topper" for our bed we got years ago from Overstock.com. The bed is super comfortable. Consolidate your tools. I have things like a screwdriver with bits so I can use it for a flat head, phillips head, and torx. Think about a screen type tarp that you can hang from your awning in case you are parked in a spot that has no shade and the sun is quite hot. I have one that I do not use a lot but everynow and then it is needed, collapsible step stool.
