Hello, we are currently looking for a used caravan with the following basic data. The bunk bed can also be foldable if necessary. After first searches seems to be very small with the offer of such caravans. Is that so? After which manufacturers and series it is worth looking? We had already discovered one of Kip which would have fit but it was immediately gone and since then one of them has not appeared again. Also a Knaus Mustang.
