All good ideas. I might add....
1. Check power and water before disconnecting at camp site.
2. Leave room on the side for slide outs and awnings. I carry a stick to use to assure I have room to operate slide out.
3. Carry a 50 to 30 amp connector plug.
4. Carry an extra power extension cord.
5. Carry an extra water hose.
6. I started out carrying stuff I never used. To solve the issue, I placed a piece of masking tape on the items I carried and when I used an item I took the tape off. After a year, any thing that still had tape on, I left home. Only take what you need.
