Well I am guessing you have a 4x4 with v8. If so I see a towing capacity of 8350
And looks like you have a trailer weight of 4300 pounds dry weight.
So from what I can see you should have enough truck for that trailer.
Now with that length of trailer you should use two friction sway controls and make sure they are set up correctly. But I would first make sure that your WDH is set up correctly. But I would really look into a better WDH for a tralier of that length.
And when you stop do a walk around the trailer make sure everything looks good and locked down as they should be. Check the hitch head even the pin that holds the hitch in place. Something I find good it get a pad lock for the hitch head once you are hooked up just lock it in place that way don't have to worry about a pin falling out or even someone screwing with it. And just check tires make sure they all look the same. Also check tire pressure before you start and fill to max air pressure. And always check tires when cold before driving to get the correct air pressure.
Another thing get a torque wrench and check the tire lug nuts make sure they are tight and then check again before you leave to come home. The right amount of wheel torque should be in your owners manual.
I think you will have a great trip. Just don't be in a rush I mean you are carrying your home behind you. You can stop any where at anytime.
