We should have known from the start that our dealings with the owner might be difficult since she was quite responsive to e-mails UNLESS they were questions she didn’t want to address. On more than one occasion, she did not answer questions submitted to her. When I went to pick up the RV, she mentioned that she might be selling it and after our trip, I understand why. This is only our 2nd time ever renting an RV and it turned out to be a bad experience.My wife and I rented this RV for a trip and encountered issues on the 1st night.When we arrived at an RV Park on our 1st night, we looked for a cable to connect to the RV Park cable for TV and we could not find one. We also realized the bed in the back was not the best since walls on both sides make it quite confined so we were going to use the bed over the cab since it was pretty large. We inquired on the cable and ladder and she said she does not provides cables and the ladder was at her house.On our 2nd night, we realized where was a substantial water leak either from the shower or from the bathroom sink and the floor was covered in clean water. We soaked up a lot of water which was on the floor so we decided to not use the shower or sink since we didn’t want to cause damage to the RV. We were only able to use the shower and sink 2 days out of 6 days.Then, while driving, the check engine light came on. Since the vehicle has over 140K miles on it, we were very concerned we would be stranded in the middle of nowhere. We took our vacation time to find a place to have it checked and were told it was the catalytic converter and that it was likely safe to drive with that issue. We were still concerned since it had so many miles that it would not have more issues. Even while driving it, it was so noisy, it was difficult to hear.We wrote her about the problems, and she said she had recently replaced the catalytic converter and was also concerned about the water leak. She asked if WE could find someone to look for the leak so we spent about a half of a day doing so with no success. She said she would look too. I also went through the firm that Outdoorsy uses (contract, I believe) and the process seemed very difficult.We were traveling again when she reached out to say she found someone to look at the water leak but we had already left the location where she found someone.We then received news that my wife’s father had a brain tumor and we decided to come back early and we advised the owner. We had another interim RV Park stop and upon leaving there to return, I dumped the black & gray water tanks so they would be empty for the return.After the return, the owner reached back to me asking questions about the water leak. I replied to her provided her the best info I had. She later wrote back and said they found the leak and that the shower would need to be removed to fix it.About a week later, I asked about the deposit and credit she previously mentioned. She THEN said that she had gallons of black water which came out on her driveway. The tanks registered empty when returned. I find that difficult to believe since I dumped it earlier that day. It would have been helpful if the owner had provided a hose stand for black and gray water to properly drain the tanks. She also said the commode had urine on it. My wife and I are very clean and particular about any property we use. We spent a lot of time cleaning the RV and if, for some reason, we missed the commode (which I doubt because I thought I had wiped it down myself), then shame on us. I asked her why she hadn’t told me about the black water she claims was there and she said she didn’t have time, but she did have time to write me about the leak and then afterwards about the finding of the leak. She claimed no credit was a tradeoff. She then said she has recent health problems which I can empathize with but that should not interfere with our rental. She also asked why we just didn’t use the shower…even after she was so concerned about it initially. I guess our trying to do the right thing just wasn’t good enough for her. I assume the cost to fix the leak was the reason she did not provide a credit.
