MY NAME IS chick, I live in Queensland Australia. Before you go throwing money at this dream. Read this. IT WILL NOT WORK. If you look at the vin plate it will have a tare weight,showing Bare bones cab and chassis weight.(tare) It will have GMV ( Gross vehicle mass) ie, fully loaded with 2 persons in the car. A car of your size will have aloading weight of?????apptox. 1.3 tonne.
So your modifications must be under 900kg, with 2 people in it. that doesn't leave room for a pair of jocks and a water bottle. By that stage the car has its arse sitting on the ground and goes like slug. SORRY ABOUT THAT. Look at the pictures of white unit SHAYNE posted ,too show you. Overloaded ,pisspor sprigs and a hanfull to drive, not too mention the tyre s exploding constantly. Bet he didn't read the tyre ratings on the tyre wall.
Over 20 years I have built 3 beauties. The first on a new 1998 single cab HI_LUX. was a failure, even beefing up the back springs, and Michelin air bag lifters. Into a head wind, it was back a gear, and blowing black smoke everywhere. Moved up to a new single cab Landcruiser,(1990) It went better, used diesel, was always overloaded and waiting for the transport police to pull me over. THE tare weight on it was 2.3 bare C/Chass, and I used all aluminium, and searched for all lightweight fittings, and it came in @3.3 tonne, it's actual GVM. That had no clothes ,water, but did have solar panel, 120 A/H battery and copper wire to connect. Then there was the aluminium boat and outboard to go on as well.
Look on Australian web sites, and you'll find many factory finished slide on's in exactly the same GVM circumstance that I've described, and they are retail smick mobiles around $40----60 thous, and are basically over loaded as you drive it out of the showroom. Think towards a 2-----2.5 tonne camper trailer out of Australia... The dollar exchange is in your favor. There are literally Hundreds of trailer builders competing in Australia , and there some real ball biters. buy an Australian magazine, I think,"Australian trailer camping", or similar name. google similar till you find it. Its'full of reviews,and ALL model names and ranges, with current prices on all models. Such a variety of Shmick trailers
But in reality I have been wasting my time writing this too you, because your mates have told you can do it on the cheap.... You'll lose money and time out of your life.-----And you can't sell it, Believe me, I've been there. CHICK
