Light weight camper trailer

I have looked at the Vision also and haven't been able to find out much in the way of approx prices....room inside for something like a portaloo....weight etc ???

My Vision weighs 650 kgs empty and with 240 ltrs of water and fully loaded it comes in under 1200kgs which is lighter than a Kimberly camper empty. Price range of the Vision from $30000 to $50000.
There is room for a portaloo in the tent that drops down from the back door that opens up and it fits inside where the steeps go when travelling ( Well thats were I store mine)
