Probably closer to 8' 6" wide. Height sounds typical. I tow something like that that's heavier in a toy hauler with the same truck you are getting.
You can get the automatic air bag option from Ram. I would not and did not. It's both expensive and complicated with questionable reliability. For what you are towing you don't really need anything done to your suspension. it might be big to you but essentially it's not and actually relatively light.
On mine I did change the rear bumper stops to Timbren's. They are like a helper springs that takes over after about an inch of rear sag. I have a large generator and twin 30 lb propane tanks on my toy-hauler tongue. That's a lot of weight. It tows fine with no weight distribution bars and the Timbrens. Still, I use weigh bars on my trailer.
Enjoy the truck. It is more than up to the task.
