    We purchased this trailer about 6 weeks ago and have been busy as a blowfly ever since. Today was the first chance we have had to get it ready for work in the new year. For the technically minded the bed is 23' 6" long and max width at 8' 2". We really needed a trailer to shift the skid and all our attachments including the rockbreaker and block lifting gear for the excavator. Its bigger than we planned but it wont go to waste.

    Current rolling/load capacity is limited by the hitch at 7,700lbs but we are getting that up to 10,000 shortly. I went to order a Hook/Ball & Pintle only to find it was going to take 4 weeks to get one and cost nearly $500 Aus. A trip to the truck wreckers found a 8 ton HBP hitch for $100 and I scored a 5 wire 24 to 12 volt step down as well for $20.

    Sorry about all the junk on the deck. Also for those enduring less than favourable climes...Please note blue sky and sunshine:p

    So anyway, we got the trailer for $5.5K which is good because it would have cost well over $20K to get one built. Its two years old (technically). The chasis and bed is off a flat bed truck so it would be good for at least 22,000lbs. However the guy who built it only needed to haul his drag car and some stuff so he only put 14" wheels with 3300lb axles. The ball coupling is also only good for 7700lbs.

    Now this trailer has electric brakes on all three axles as well as the electric breakaway system which is mandatory on all trailers over 4400lbs. Our Mitsuibishi 9 tonner (20,000lb payload) is all 24 volt. My initial thought was to just change the trailer light bulbs to 24 volt and we are away. However, the braking system is also 12 volt:confused: .

    So, Step 1 was to get the lights sorted. As mentioned above, when I was at the truck yard getting the Hook and Pintle hitch I spotted a 24/12 step down unit fitted on a wrecked truck so I grabbed that, $20 for a $160 pice of kit and it works!. Climbed under the back of the truck and looked at spagetti junction:dizzy: . Did about 10 minutes with the test meter then chop chop chop with the wire cutters and started again. (The truck is ex-municipal council).

    Rewired the number plate light, reversing alarm, fitted the step down and ran new wires to the trailer plug. Tested everything and hooked it up to the tools trailer which has dual voltage LED lights. At first it worked fine then the LED's started to get dim and not work. Testing under load showed 8 volts??..so I thought the 2nd Hand step down was junk. Then I hooked it up to the new trailer which has all filament bulbs and it holds 12.8 volts and everything works. (mental note about step downs and LED's which run up to 24volt).

    Step 2 - will be to fit the HBP hitch to the truck (as recommended by UNISCAPER) and fit the 3" ring to the trailer.

    Step 3 - will be to fit a combined step down power supply and brake controller in the truck cab. This is the one I'm looking at:

    Then I suppose after that it will go to the DOT to get the GVM uprated, then it will need a tool box or three, racks for gear, fuel tank for the skid, tie down chains etc etc:) . I forgot to mention, the trailer has a 26 (US) gallon stainless steel water tank mounted under the back.

    I think it will be worth it. The bug bear is that the GVM is limited by the wheels and axles. It may be worth replacing them with something more substantial in the future but when we go over 10,000lbs air brakes are mandatory which will mean half the time and money I'm expending now will be wasted...:confused: but we will see.

    Sorry Squizzy I normally read more than I post but it seems to me you got a good deal on the trailer and you only had to put a little work into it to make it right. I have a question you said once over 10K vehicle weight you need air brakes correct? Now will that require you to have a CDL? & is the weight rating TOTAL weight or what? The reason I ask is because here in the States it's 26,001lbs or more then you need air brakes and a class A CDL.

    You got me there, whats a CDL?. I must admit I have trouble keeping up with the regs as they are changing here to try and have national regulations rather than different between each state. GVM is Gross Vehicular Mass or Total weight. We used to have just Tare = kerbside weight unladen, Aggregate = Total Payload and Gross = Tare + Aggregate or GVM.

    No need to apologise I was just stirring a little :blush: ... but thanks for the reply:)

    CDL= Commercial Drivers License. Here in the states as I said anything with a weight of 26,001lb or more needs one of these. Do things differ in Australia?

    Yep - I have a MR (Medium Rigid) License, thats for two axles (on the truck) and load not exceeding the GCM (Gross Combination Mass i.e. tow vehicle + trailer) of the tow vehicle. I think the GCM of our Mitsi is about 52,000 lbs. To go heavier that would be a HR. See the link:

    It's basically the same thing as here in the States just worded differently. This may be a dumb question but do you have ramps for the trailer so that you can get your skid on it? The reason I ask is because I did'nt see anything in the pics. Now after you get everything rigged the way you need you need to get some pics of the whole rig loaded out.

    We do have portable ramps for the truck but spring loaded fold-ups will be another item for the trailer to-do list.
