Wheelchair loading in vans, T5, Viano etc.

Hi together, I have used a Carolift 6900 so far for the loading of my electric wheelchair into a VW-Caddy Maxi. I have set pictures under my then contribution to the Carolift 6000 and 6900 respectively. Now I say goodbye to my Caddy. Do not ask for the reasons. I am now looking for information about the loading of mainly heavy electric wheelchairs in Van, like the VW Multivan T5 or the Mercedes Viano. I have looked at the usual pages in the net shcon. I’m happy if you could present your loading system with your own pictures as much as possible. I’m interested in e.g. the underfloor cassette lift K90 (side sliding door) or a linear platform lift (vehicle rear or sliding door). Do you have pictures of this – which vehicle you drive? What are your experiences with the lifts ? (winter, curb, reliability, etc.) My E-Rolli : a Meyra Optimus II with electric legrests weighs 150 kg and is really quite large. kurkassettelift carries 300 kg and the linearlifter about 350 kg. The linearlifter is also available with split platform, which then works sideways into the vehicle. In addition, there are probably two different suppliers of linearlifter. Bruns and Apen. What are your experiences? LG JoJoMS
