Cargo Carrying Capacity

OP, you still have not said how much of the year you will use your 4018. We keep our rig stocked with non perishable food, four season cloths, lots of spare parts and tools and we do indeed use half of our 9000 CCC. When you do not have to worry about CCC it's easy to use more than you think.
Getting on the road takes less than half a day as it's clean out the home refer, get the Sat receivers, and close the house up.
