For shipping large items like this, you should look into local movers. They can load and unload the camper.
Another viable option is
U-Ship. Its a web based shipping Ebay sort of thing. You set up an account, describe what you want picked up/delivered, size, color, shape, weight, taste, smell, everything. You give est. dates, etc. Maybe even give a price as to what you are willing to spend. Then have people/shippers bid on it. Its just another way of listing and contacting others for shipping/hauling during their travels. I'm not sure if there is a fee to be paid.
A buyer of my ambulance box used this site and was happy with his use.
