Greetings from the Florida Panhandle
First off, welcome to the Forums. We're glad to have you with us.
I think that you will be able to get by with that combination, but you will really need to be set up properly. A quality sway control/weight distribution hitch system is a must when your tow vehicle/travel trailer combination is close to the limits. You will also need a quality trailer brake controller.
There are many threads on these Forums on this matter for you to review.
Good luck in your pursuit of Airstreaming.
