We were camped in Webster, WI last Memorial Day weekend. The park was small, and the owner (who was drunk when we arrived) had invited all his friends and family for the weekend. There was loud noise and music all day and well into the night. A young couple was parked next to us in a brand new TT and had a small son with them. This was their first RV outing ever, and they were about to give up on RVing. We befriended them and told them that this park was not the norm for RV parks.
When they decided to leave, they discovered that their sewer hose was too short to reach the sewer hookup. In addition, the park owner had installed the hookup about a foot above the ground. The young fellow came over and asked for advice. I took my sewer hose off our rig, and we dumped his tanks. It required lifting the hose and "milking" the contents uphill to get things to drain. When we were through, I remembered I had a spare sewer hose, so I gave it to them, in case they ran into a similar problem in the future. They were so grateful for our help that they kept trying to pay us. I, of course, told them that no payment was necessary and that, perhaps, they would one day have a chance to pay it forward.
I hope they are still RVing. It would be a shame if a thoughtless RV park owner and his boisterous friends spoiled their dreams.
On the receiving end, DW and I were traveling through northern NM one time, when we realized that something was amiss. I pulled over and got out to check. The right rear tire on the towed had blown and was literally gone; the car was rolling on the rim. I got out the jack, which I had never had occasion to use before, and began figuring out how to jack up the car. About that time a fellow in a battered old pickup pulled up with his father and his son with him. He said, "Here, let us help." Before I could protest that I was okay, he had pulled a hydraulic floor jack out of the truck bed and jacked up my car. In about 10 minutes, the tire was changed, and he had told us exactly where to go in the next town to get a new tire. They all piled back in their pickup and away they went.
Our experience is that most people we have met traveling are friendly and love to be helpful.
