Thanks for the welcome and comments
I have a heap of photo's of the build so when i get some time I will put them into a My camper trailer build.
We tow the camper with a GU3 Nissan Patrol 3.0 Diesel you don't feel the camper on the back until you hit a hill and then it tends to slow down a little.
The weight of the camper is about 1100 kg dry.
We spent the last school holidays at Twofold Bay near Eden and had no problems fitting onto site. We had rain for the first 3 or 4 days but because of its size we didn't get under each others feet.
I do use a braked winch to raise and lower the floor but with the gas struts and the roof rack that acts as a counter balance my 10 year old son can raise and lower it.
