We are thinking of buying a swan outback but we were wondering if an extended drawbar is useful if doing an overnight stop whilst still hitched to the car . Can the beds be pulled out all the way on a standard outback drawbar without hitting the rear door or would I need an extended drawbar. Has anyone done this on their swan ?

I googled a Swan. There is a good picture of a drawbar with a 2003 Swan with beds extended. It seems the end of the bed is directly above the towball. Another 300mm would be handy for a wagon tug set up imo.

I had an extended drawbar on a camper and it made balancing more difficilt so keep it to a minimum.

An extended drawbar means less downforce on the towball. Good for a Kluger I would think. You may even be able to open the rear gate while still hitched too. Not sure of sizes or actual clearances involved there!

Unsure what the above comment means with balancing. If moving by hand it would be easier to some degree.

The longer drawbar may also be beneficial when backing the unit as it will be slower to react to steering input, but might also be restrictive into tight circumstances.

Yes, sorry RMD i ordeted a camper with a 400mm longer drawbar to make way for a toolbox. It was the toolbox and its contents that increased the towball weight. Rather irrelevant to this post.

Extended draw bar means more weight on the tow ball, not less weight.

Yes there is more weight in the draw bar itself but you are putting the main weight further back so the chances are that the weight on the tow ball will be less. It you had a really short draw bar of 30 cm ( example only) it would weigh very little but the main weight would be on the tow ball making that tow ball weight very heavy.

Dear Jonnykluger

Suggest you visit your local Jayco dealer with your tug and check out the clearance issues.

I had a look at the Outback specifications on the Jayco website and it looks like the forward bed extension covers the tow ball. But it's hard to determine. Link

I have a Prado with the big swinging rear door so a tow bar extension was needed otherwise access to the rear, whilst towing, would have been impossible.

The extension will give you better manoeuvrability when reversing. However your towball weight will increase. Jayco states the Tow ball weight for the Outback is 109kg. The distance from the tow ball to the van axle looks to be about 3m. If this is the case an extension of 400mm will increase the lever arm by approx 12%. So your towball weight will increase by the same amount plus the actual weight of the extension. If the extension weighs 15kg (just guessing) then your final towball weight will be 109kg + 13kg (12% of 109) + 15kg = 137. Calculation is not precise but will do as an approximation.

Cheers John

The laws of physics and simple levers apply here. If you extend the drawbar with a weightless extension and nothing else is changed the towball weight will be reduced.

A weightless extension is pretty hard to find LOL. The towball weight reduction will be offset by the weight of the extension device, so in real life there may be little or no net change and perhaps an increase.

Frank is correct.

The estimation I supplied previously is wrong. Where it shows +13kg the number should be -13kg. Not sure what's happening to the brain these days to make such a basic error. Don't let me design your next wheelbarrow.

Cheers
John
