Average cargo load for retired couple fulltiming?

Thank you! So now I am looking at a 5er with 2,726 lbs CCC as per the "yellow sticker." I think that just MIGHT work for 2 of us? I will need to add a small fridge, sewing machine, and I make soap and beauty products, so will be carrying a good bit of oils with us.

Tell me....does this CCC apply to being towed only, or does it also apply to sitting on a property to be lived in for a year?
