Thousands, likely tens of thousands, of motorhomes site for longer every year. Not a problem as long as you follow basic maintenance guidelines above.
One thing I was not prepared for with full-timing and volunteering for months at a time was the sewer hose. I know to cover my tires and protect external plastic parts as much as possible from UV damage. Didn't think about the sewer hose sitting out in the sun every day for months. It does get damage from UV and might lose flexibility along with developing cracks on the top side.
