Here is a link to a website that has checklists for stocking your RV as well as pre trip inspections etc.
RV ChecklistsI keep my hoses in bumper and the adapters in a sealed plastic tub. I use the Flush King which allows me to rinse the hose out when done dumping tanks. I also always wear gloves when handling anything related to the sewer system. I occasionally fill the tub with a disinfectant soap and let the stuff soak then rinse then air dry and then back into RV. Never had any issue with smells.
