We were first-timers at this RV thing. Fortunately, we were going with my friend, who is a pro, and he helped us out. The only problem we had with our rental from Martin RV Rentals was the gray water and the black water. I now know it is usually emptied before starting a trip, and ours wasn't empty, it was nearly full. The first time my wife and I took showers, it started backing up on my wife. Then we discovered that with full black water, we also couldn't flush the toilet. It was clogged. It took two or three hours with my friend helping to clear the clog. It never fully emptied. Other than that, it was a nice trailer. I might get one with a full-size bed next time because the foldout style wasn't very comfortable on my back. But there is no doubt that we'll do it again. Overall, it was a good experience renting from Martin RV Rentals. Next time, I'll be more knowledgeable about the details.
