Part of being an American is abiding by the laws of our Country and Municipalities.
As a Marine I am always happy to see a fellow American fly a flag. There is one flying 24/7 in my front yard. The size of your flag does not denote the size of your patriotism. The company applied for and was given permission to fly a 25 foot by 40 foot flag. If that flag is not large enough to show that your patriotism exists, what is my 2 foot by 3 foot flag doing?
Like was said above, the grossly oversize flag is being used to attract attention to the business. And I would bet it is being deducted as a business expense that would prove it.
Marcus, if you want to really support the Veterans you are using to defend your breaking of laws, start insisting that every RV manufacturer produce at least one model of RV that is ADA compliant and affordable.
