Hi and welcome to iRV2
Just a quick look and you can probably pull the trailer, I don't know if you are within ratings or not. you need to weight the truck and trailer and see where you stand weight wise.
It will not be a comfortable tow, as you will be towing in 3rd and lower gears in the hills with an engine that is screaming in the upper RPM range. Expect to get 7 to 8 mpg at 60 to 65 mph.
I am not a big fan of the 5.4L for towing. The later models with a bit more power do a bit better. They do not seen to have much power and really like to visit the gas stations.
Personally, I think you are pushing into the 3/4 ton truck range to have a comfortable trip towing.
The Reese Dual Cam HP is a great hitch and once set correctly for a loaded truck and trailer will perform well. Read the Reese installation manual and follow through the hitch set up and learn how to set the hitch properly.
