We have several choices for replacing the mattress in your Gulf Stream Tour Master. If you have a queen you'll need to measure the length to see if you have a short queen which measures 75" long or a standard queen which measures 80" long. The etrailer eDream Deluxe RV Mattress is our best option and what I recommend, part # e84FR for short queen or part # e24FR for standard queen.
I have attached our full selection of queen mattresses below as well. view full answer...
