Good luck! Just like you said, if you don’t have it just go and buy it. Not that big of a deal. Not sure if this is your first travel trailer, but either way definitely take it slow and easy. That is a really big trailer for your truck. Not trying to be a downer, but just realize you have a lot of trailer for your tow vehicle. I’m sure it will a great trip and if you have any questions or concerns please use this forum, it is awesome. Safe travels.
