Welcome, glad you're here and asking the important questions before jumping in w/both feet. The Passport is a great trailer and floor plan. Our daughter has the same model. It works really well for their family of 4.
Now the good news! Father's day was just a few days ago and what better late Father's Day gift than a new truck for Dad
