After looking at one imported camper in Sydney (I won't say anymore), I decided that I would assemble one myself, using a quality built off road trailer and "reasonable" imported tent. After visiting a trailer maker, I have ordered a trailer as follows: 7 x 4, Off Road Trailer, Fully welded box, 7 Leaf off-road rebound suspension, shock and vibration proof fully sealed LED lights, 4 x 50 x 50 mm tube chassis, 4 x 75 x 50 mm tube drawbar, 45 mm axle, 6 stud hubs (Patrol / Landcruiser) brand new sunraysia wheels (15x7), 2 jerry can holders, 1 9kg gas bottle holder, rear support stands, 1800 mm long drawbar, swing tailgate on rear, water tank with guard, tap and filler, electric brakes, stone guard, Chequer-plate floor and mudguards and Chequer-plate jerry can stone guards, poly block coupling, rear bike/recovery mount. I also came across a tent importer who appears to stand by the product, provides you with his phone number, email etc and a reasonable warranty. After answering all my questions he gave me a great discount (probably got sick of me), so I am now in the process of buying all the other bits and pieces to make this suitable to our needs. I hear "Lost's" echo in my head, therefore I am keeping a spreadsheet, detailing every cent. I will probably start a new thread in "My Camper Trailer" section when it all arrives, ready for me to start tinkering.
Cheers
Andy
