Greetings from the Florida Panhandle
That's a really interesting question.
I have considered this very issue on Lucy, who recently weighed in at 7400# ready to camp.
After Lucy's recent 8 week California adventure, I took everything out of her that I thought that I could possibly do without on the road.
The grand total of the removed items was 154#.
I immediately put all my stuff back.
