In short, not a camper for people who's first camper trip it is or people who mind an old camper. If you don't mind that, it's a good price and can bring a beautiful experience.
When we arrived, the camper was brought by another guy than the owner of the camper, which is understandable and can be totally fine. For us as newbies to a camper however it was a problem, since the guy didn't speak english very well and did not know himself how the camper worked exactly. So during our holiday we had to text the owner a lot of times with questions, he did always respond nicely to our questions. Also shifting with the gear box if you are not an experience driver can be very difficult with this camper, make sure you know what you begin, it made some roads in Portugal pretty stressful for us. But again, if you don't mind this doesn't have to be a problem. Also the camper has a high fuel consumption, keep that in mind as well.
Also make sure you check everything before you start driving, in our case the guy who brought us the camper, forgot to close on of the small windows next to the sleeping compartment. When we arrived at our first destination, after driving for two hours on the highway, the window was gone, due to the wind and the fact that the guy left it open. This problem could not be solved so we had some cold nights.
The last issue was for us the most important one, and that's due to the fact that it's an old camper. While we drove on the highway, the motor got overheated. We stopped and asked a guy to check it at a gasstation, who told us there was water and rust in the coolant reservoir (there supposed to be coolant in there, not water). Therefore we couldn't drive any further. The owner has responded correctly by picking up the camper and refund us the rest of the nights.
Overall we had a nice vacation in Portugal, which is a beautiful country. If you don't mind it being an old camper, you can have a nice time with it. Just make sure your expectations are correct.
