I know I don't have a MH but as silver has said I try every year to get a little lighter. Lighter weight lawn chairs, a gas grill /stove and a very small charcoal grill and just as much charcoal as we need for that trip. We didn't need a kitchen service for eight cut that to 4. Pots and pans aluminum and just the basics. Water Hose was a big item i got rid of, kept 50 ft of white hose but got rid of 200 ft of regular hose and got 200 ft of that light weight expandable lost 30 lbs doing this. Expandable works great for filling water tank without moving to get to spigot. Next weight loss wil be tools and setting up a basic tool kit bet I can loose 30 lbs there.
Think about things before you do them make life easier not harder.
