The ProMaster chassis warranty is 3-years/36,000-miles and 5-years/100,000-miles on drive train.
The warranty starts on the day you buy your new Travato, and this goes for your complimentary 12-month SiriusXM subscription as well.
Winnebago offers a 12-month/15,000-mile basic warranty on the coach as well. Some of the appliances and accessories in the van come with their own warranties too, so make sure you refer to your owners manual.
