Here are a few important things to know about shipping an RV:

Transporters accept cash, credit cards, or certified funds for the deposit. They normally accept the balance in the form of cash or certified funds, unless other arrangements have been made with them in advance. 

Deposits are normally accepted in the form of credit card, money orders or certified check, and sometimes even cash. Usually, the only form of payment accepted for the remaining balance due on delivery is cash, money orders or any other form of certified funds. Check with your transporter to be sure of their payment policies.
