I have owned two Keystone products and have been happy with both. The Sprinter line is on the lower end of Keystone products, and not sure I would want to full time in that level considering R values and overall durability for full time use. I don't believe the warranty is valid for full timing with the sprinter. Check the Keystone Sprinter warranty fine print before you proceed.
