Hi
I have a slide out tray from 1sternehotel and it is the best modification I have made to our MP. It makes a two week trip so much easier with room for everything we need. I have bought from 1sternehotel many times and their service and delivery to the UK has been great, just days.
You can find the tray here,
Heckauszug für den Mercedes-Benz Marco Polo W447 & Viano Marco Polo W639 oder Mercedes-Benz Marco Polo Horizon & Activityzusätzlicher Stauraum, mehr Komfort zum Campen, Arbeiten oder im Alltag. Heckschublade für den Marco Polo im Zubehör Shop 1sternehotel
www.1sternehotel.de
I load mine with 5 front runner cub boxes which slide under the bed frame with about 10mm to spare but maximise the space on the tray.
Final point to make is you don’t need to lose the table and chairs. 1sternehotel also provide a tub that sits into the bed frame above your sliding tray. I swapped out the MP chairs with the compact folding front runner chairs and they slide into the tub very well.
All pictures are on their site.
I hope this is useful to you, I find packing the MP to be an art that is never finished. I’d welcome any other ideas that are out there.
Thanks, Michael.
