Charlie, i don't know where it says anything because i don't have a manual. Our SMB is used.
However on their website... under general info page it says
http://sportsmobile.com/5_general-info.html
"Sportsmobile's Warranty?
Sportsmobile’s limited warranty is the best in the RV industry — 50 months or 50,000 miles.
All of our tops are warranted to be leak proof for as long as you own your Sportsmobile. Appliances, such as the refrigerator, furnace, hot water heater and air conditioner are warranted by their respective manufacturers. The van chassis is warranted by the manufacturer — Ford, Dodge or Chevy/GM. See the Warranty page by clicking menu button under Information."
I'll email Lynn tomorrow and ask her.
