Hi Mike and Karen. I looked at Gulfstream's website and it states the following:
TWO YEAR UNLIMITED MILEAGE TRANSFERABLE WARRANTY on structural components!
One year unlimited mileage total use warranty under normal use against defects in material and/or workmanship in construction and original components.
* For purpose of this warranty, "Structural components" shall be limited to the structure of the side walls, front and back walls, roof and floor.
You will find the warranty info near the bottom of the page.
