The leaf springs and live axles on most pickups need to be loaded to some extent to achieve optimum handling. As the OP has noted, unloaded does hop around quite a bit, particularly on rough roads. The technical term is axle tramp.

I knew an axle tramp once.  She was only interested in me because of my wheels.

You are correct getting confused with my wife’s car it was a Vigo,

No Vigo 5 years ago.

 Yes it was getting confused with the names but apart from that issue ever had a problem

As far as the comment by” anythingleft” we were were not speeding as it would be impossible or suicidal on that stretch of road which we travel regularly and know well

I can only assume that it was an unusual set of road conditions, Interestigly enough about two months later we saw a similar model in exactly the same position as where we ended up coincidence perhaps ?

Must learn the ups and downs of a ride...A pickup ain't a saloon....

Exactly have driven pickups in Australia on and off for years with no issues  but interesting that the new model has a stabilizer fitted also read some commentary from South Africa about problems experienced there

 Never had the same problem again and borrowed the vehicle only last week for a 6 hour round trip using the same route

Sorry I thought it was  “ dig “

after this happened which was about 5 years ago I spoke to the local Toyota dealer from where it was bought and were quite helpful

They recommended a place who seemed to know about the issue and suggested fitting a stabilizer similar to what was fitted to the Fortuner

Its really like a big shock absorber and seemed to do the job

You could feel it pull the back down and fortunately never had a problem after that time

Hey, up to you. Fill the back full of crap if you so wish
For me never had a problem with the pick up that I own, and it does a lot of miles. As another poster replied -drive within the limits of the vehicle and the road conditions- quite frankly if you do that then you wont need to put any weight in the back or modify the vehicle in any way

Never mentioned putting anything in the back at the time was driving well within the limits I just love the arm chair experts

There's a lot of pickup owners here, me included, and in the 6 years I've been driving them never had the back get away from me, but even a sports car will do a 360 if not driven to either the road conditions or just badly.

Or sometimes the road simply requires traction. And without load that can be impossible for trucks and minibuses.

I guess if you live at the top of a mountainous dirt road or in the Alps.

Must admit I lost the rear of an unloaded HGV rigid truck once, frightened the life out of me.

Or here in Thailand, where I know one road where I see on many occasions car slipping backwards, unloaded trucks and unloaded minibuses.

Is it worth loading up your pickup with sandbags for a road you may never use? I guess it does depend where you live, but in 7 years have never needed any more traction than what I have, ie an empty pickup tray.

I have occasionally felt my truck trying to dance sideways on some straight, bumpy roads.

Perhaps a shock-absorber upgrade would help to improve that situation?

I believe only leaf springs on the rear of a pickup.

You may not drive those roads, but the OP, who asked about this since he does experience problems, apparently does.

In that case, sandbag away!

4 bags is equal to a 200 pound man sitting in the back,  Does not hurt my economy a bit.  I run between 14 and 15 kilometers per liter.

in fact it will help also with breaking as it will add to the down force.

but the issue is not stopping distance but the back end sliding out. what are your thoughts on that mr scientist?

The issue was braking and, therefore, stopping distance according to the post that he was referring to Mr Not-A-Reader.

You may not have measured the difference but for the same road conditions and the same driving technique it is impossible to load a vehicle with any weight and for that weight not to affect the amount of fuel needed to move the vehicle the same distance and speed. It is just not physically possible.

You're correct, I'm wrong.

What he said.     Finally, another poster that has some knowledge of the laws of physics.  I do not fault anyone's input on subjects that they have some actual knowledge about.  But, when their input demonstrates their lack of knowledge or common sense, it requires addressing. 

I do .......at some of the posts....

Great, helpful answer. 

A new truck that I bought one time was doing just this, after 40 years of experience driving trucks and it was a white knuckle drive all the time. After being advised to put a heavy steel plate in the back (and accepting increased fuel usage)  I eventually changed the tyres, problem solved. The tyre seller said I wasn't the first to have this problem. 

Don't worry about sandbags and stuff, your experience was quite possibly due to a false combination of tyres to truck.

Or the wrong truck, they should after all, be designed to be driven fully loaded, not empty, but this shouldn't be a problem on newer models
