I didn't see a 260 kls model listed on their website when I looked, so other than the previously mentioned "what kind of tow vehicle are you using", the only thing I can offer is to make sure that your camper is fully functional with the slides in, if that is important to you.
In the Spree we almost bought in 2012, there was only 1 door and with the slides in you could not access the bathroom or the bedroom. (We though it would be inconvenient to put out the slides every time we wanted to use the potty while on the road.)
