matt has it right. you may be able to get an extension if it is a repair needed to make the coach unusable. if you can use the coach without the generator, then its usable. if it has a broken door lock, its not usable. it depends on defining usable.
if it is a minor problem, typically they wont do anything. the key is whether it was usable or not. note i said minor problem. to coach owners, there is no minor problem, but legally there is. an open and frank discussion with the general manager will help a lot.
heres a tip- never tell the service adviser that theres no hurry. get a completion date when ever possible.
