Most have a clause such as this in the warranty docs.
"The Warrantor further makes no warranty with regard to any product used for commercial purposes, as a permanent or full time residence or as a rental unit, or any product not registered and normally used in the United States or Canada. For purposes of this warranty, it shall be deemed conclusive evidence of commercial purposes if the product is licensed, titled, registered, or insured in the name of any corporation, LLC, or any other form of business or commercial entity. "Full time" for the purposes of this warranty shall mean continuous occupation of the Recreational Vehicle for a period exceeding 30 days or 18 days per month in two or more consecutive months"
As well as something slyly worded like this in the manual which does not direct you to the above in same manual.
"Your recreational vehicle was designed for recreational use and short-term occupancy."
Too many geezers, self appointed moderators, experts, and disappearing posts for me. Enjoy. How many times can the same thing be rehashed over and over?
