Have you driven one yet? I really liked the look of these and had one for a week as a courtesy car, I found it pretty uncomfortable and couldn't wait to give it back. That's just my personal experience but I wouldn't fancy doing a long trip in the car I had, perhaps some of the versions have a better tyre/suspension set up that makes them feel more comfortable. You don't see many towing caravans either. Many of the Peugeots have very low noseweights so that's something else to look out for.
I would not tow a trailer with one, they are far to light on the front end and cost of the towbar is high, you will also have problems with the fuel system it has a adaptive system that is consistently learning and most of the time it is 'pinking' not a good tow car, plus as said earlier low nose weight a very light body weight. I have had one for two years and will not be getting another peuguet.
