You probably already know this but you cant use a weight dist. hitch on a Class C. I would be gathering all the advertising info including print outs of the web page and demanding that Thor make this right. They are not allowed to advertise one thing and sell another without telling you. I am sure you will get resistance. Even if you make all the upgrades the VIN will still be an E350 and any overload condition could get you in real trouble if you had any mishap.
