Overhang calculation non-USA countries

[Fred Skywalker]

Wondering if someone can help me understand the overhang calculation that many countries have outside of the U.S. I understand the 60% of the wheelbase part but I'm confused on if anything attached to the back of the camper is part of that calculation or is it considered a "projected load". For example, lets say the finished camper comes in at the maximum length of the 60% calc without a spare tire. Now lets add a spare tire to the back. Does that put the truck over the limit or is the spare tire considered "projected load".

Hi Fred.

The way I understand it, 60% has to include everything (including spare wheels). This is why I recessed the spare wheels in under the body on our build. Here's where you look if in Australia:-

The rear overhang of a vehicle is the distance between the rear of the vehicle and the rear overhang line of the vehicle.

That was my understanding as well and then I started reading the Aussie sections on "projected load" and then I wasn't so sure. Projected load applies to say a pickup truck carrying wood that's longer than the bed. The legality of this is defined under the projected load section. So I wasn't sure how a spare tire or say a motorcycle rack would be treated.

I'm guessing that if it's bolted on it's part of the vehicle, but if it's tied on, then it's classed as a load...

Yes, any lifts or permanently mounted racks etc is part of the calculation and that would include spares or any motorcycle lift. At least in Norway which normally follows EC laws..

I took this from the local Dtp of transport - was on the wall. Basically anything that stick out the back can't be more the 60% of the wheelbase.

Thanks guys, I appreciate the comments and the confirmation that the 60% rule includes everything on the back.

Better to know that now than build a fantastic rig only to be told no at the first foreign port arrival.

I do this a few times a year. Luckily I live rural.

I'll raise you both... The tray is at 60%... The journey home was a steady one via dirt roads and with my fingers crossed!!

I think in most cases you would not have an issue if the truck is legal and follows it's country specific rules concerning rebuilding. I do not think the host country would/could impose its own vehicular rules for guests?
I know Norway has rules for over 3500kgs vehicles having "official" snow tires but apart from that I dont think even the road administration here would go that far, unless it was obviously unsafe and ridiculous..

I did hear of one of the GXVs or Unicats with some extra storage boxes and a spare tyre at the backof the truck being refused entry here in Australia becasue of the 60% rule. They took the boxes off, returned to the rego office and got registration. Then put the suff back on. There are certain things they will give temporary exemptions for, like a Left hand Drive, but some rules are enforced strictly. This is Ron's truck.

Here is a link to his blog - he doesn't mention it.
