It happened to me last summer on the way back home after a month long road trip. We had reservations and stopped for one night at the KOA in the small town of Jackson, MN. While we were camping on this road trip, I always made reservations for campsites with both water and electricity. I was feeling very ill and it was a struggle for me to set up camp (tent camping). After going to bed for the night, I woke up GF and asked her to take me to nearest emergency room. I ended up staying 3 nights in a 13 bed rural hospital in Jackson MN, a surprisingly modern facility.
GF talked to KOA owners about me being in the hospital and extending our stay. They were very understanding and could not have been nicer. In fact, owner told GF to stay as long as needed and even helped her break down camp when I was released from hospital. I was still very sick and weak when discharged. Owners also told GF that they would not charge for any extra nights at KOA. Perhaps because we were old baby boomers camping in a 40 year old tent, they figured we had limited resources. Not sure they would offer the same no charge for additional nights for someone in a $100,000 MH, but maybe.
I suspect most RV campground owners/staff would be understanding and make accommodations in a similar emergency event. Just need to explain the situation and ask for help.
Let me follow up by saying I highly recommend the KOA in Jackson MN which is just off I-90. It has nice facilities with a fairly well stocked store, roomy spaces with a lot of trees for shade, and, of course, wonderful, friendly owners.
) It turned out my severe illness was due to an extreme reaction to a tick bite (Rocky Mountain Spotted Fever).
GF was a trooper. I was so sick that GF had to deal with the thought that I might pass away. I still tease her that she was most worried that she would have to drive the 1,300 miles home with me in a body bag in the passenger seat. ;D On the trip, I had always set up the tent, used the electric pump to blow up and blow out the air in my queen size, high loft air mattress, set up the Coleman camp stove and other camping equipment, and did all the cooking and coffee making. Plus, it took a lot of care and planning to store all that equipment in the car along with our 80 lb hound. She just couldn't get all that stuff back into my 4 door sedan. So, she made an executive decision to throw away the tent and all the bedding that she couldn't fit in the car. In addition to all that, she had to deal with the dog who became so depressed about my disappearance that he stopped eating. She had just about reached her stress limit by the time I was discharged and she picked me up from the hospital with the car already packed and ready to hit the road.
Now, for the rest of the story. The ER staff did not diagnose my allergic reaction as being cause by the tick bite. It wasn't until we return home that I saw my primary care doctor who diagnosed me as suffering from Rocky Mountain Spotted Fever. A couple weeks of high daily doses of antibiotics cured me. On a side note, it is now medical protocol to treat any tick bite with a regime of antibiotics.
Also, GF and I decided that we had done enough tent camping in our lives. Upon getting home, I immediately started looking for a travel trailer and tow vehicle.
