To determine the correct treatment, consider the RV's permanence, utility connections, and business use.This post does not create a CPA-Client relationship.

@John Voychick I'm so sorry to hear about your experience, it really pains me to hear about people getting subpar treatment and customer service I always listen to people's experiences to make sure that I can prevent these kinds of things from happening to my clients.

Then based on @Michael Baum's suggestion, I think I will have my cleaner and/or maintenance person do monthly/quarterly maintenance like using using enzyme based cleaners, grease fighting drain treatments and hot water flushing. 

some areas have septic tanks but the city or county pumps them regularly and then hauls the waste to the central treatment plant for disposal this is where leach's fields dont work..

The court seemingly implied that they could but simply failed to do so.At this point, without a more thorough research, I tend to conclude that the IRS excluded H/W LLCs from the QJV treatment arbitrarily, without statutory support.

No problems with rust but do have to deal with hard water; they have a chemical treatment called a pillow that takes care of that.

The tax treatment in such cases may vary depending on specific circumstances.

@Tom Rairdon If you’ve owned your short-term rental (STR) for over a year, it likely qualifies for long-term capital gains (LTCG) treatment, taxed at lower rates (0%-20%) compared to your 33% ordinary income bracket.

Many business owners are deeply concerned with the future treatment of their employees, equipment, image, customers, etc.  

From what I see all the people answering to me here (and there are so many) are just coming against and refusing to agree with my simple statement: "a landlord is not above the law or norms by its personal choice or presumed capability to judge what he don't know" or as well "a landlord cannot deny or miscarriage a service to a stranger without a known valid reason and at the same time pretend to be operating professionally or loyally to the moral"Basically I'm telling if you are not able to do your business correctly it would be better to find someone else than you, mainly when your ideas about "squatter" or fair treatment are coming from ignorance or completely invented.
