Tow Weights are confusing the heck out of me! Need Help

My suggestion is to go here and do some reading. This is a good site which just gives you good, reliable, straight up information. Read up so you can understand everything that is involved. But With a payload of 2166 on your truck, both of those trailers are going to be over the trucks ratings.

The fact that they are 5th wheels means they eat up a lot more of your trucks payload. You can tow a lot larger TT than 5th wheel with any given truck.
