To answer the question you would need to tell us how much your loaded trailer weighs. We could hunt down the tow capacity of the RV, but not the weight of your trailer. You also need to consider the need for trailer brakes. Brakes are always good, but if the trailer is 3000 pounds or more, you are definitely going to need them. The Sunseeker E450 has a socket to add a brake controller, but you will need to supply the controller.
