@Sandra4849 What is the most economical option for you? Do you wash the linens in your RV yourself when it is used by you? Then do that if you have the time and the machines.
If, however, you have hired a person to clean the RV after a rental, then arrange to have that person handle the laundry and make sure that they have a full set for exchange in the case of a quick turnover or damage to the linens requiring treatment or replacement.
