RV & Trailer Towing Guides | fleet.ford.com

 

I glanced at the linked guide, and I think this combination is over the limits. Maybe not by much, but still over.

One thing the guide does not go into is what adding truck options do to the towing capacity. The linked guide lists the maximum capacity for the trucks with only the equipment needed for towing and no other options.

 

It doesn't do anything to the towing capacity, as long as you don't exceed the GCVWR.

 

Watched a video from BTBRV on a dump trailer made by this company. They seem to have a good philosophy on where to build strength and where to reduce weight.
5k cutter sounds like a 15' bat wing unit. So with all that weight I pulled this up for your quick review.
The more choices you have and a few calls may help you decide. Good luck in your search.
