Plunger
I have recently acquired a Trackabout Safari CT which is matched to my 100 series Cruiser. One thing I hadn't really anticipated was the draw-bar weight - and the impact on the Cruiser - which drops quite a bit in the rear-end when the rig is fully loaded.
The axle is set
well aft on the CT and I don't see much opportunity to improve the draw-bar weight by loading differently - at least not until a few kids leave
home and I can shift the fridge off the draw-bar and into the car!
I'm not sure whether the way forward is in heavier springs?? I imagine others have addressed this situation before. Any solutions??
Regards

Plunger,
I put Firestone coilrite airbags in my rear springs to stop that problem, Worked a treat.
Polyairs are probably just as good.
Give TJM or ARB a call.
There will be people on here that will tell you to try Trucksprings in America, All I can say is don't.
I got caught out and it cost me a lot of money, The reason is they don't have 100 series Landcruisers in America.
Hope this helps
Regards

If you are towing this van for a lot of the time, or are on the road with it weeks at a time, then I would look at replacing the rear springs with heavier rate springs.However, if the towing is occassional then look at Polyair springs as an additional boost to your rear springs. Give Pedders
Suspension a call, they will be able to help you with either option, or both.

Thanks mate - I took your advice. Strongly advised by Pedders to consider 40% heavier coil, plus polyairs plus heavier shocks.

Yep - welcome to a big issue that hoards of campers have has to address - zillions of words have been typed on that subject in hoards of web and magazine forums. I used polyair bags (from Truckspring - ordered
mine without a hitch - they have Jackaroo's in the US ! - fitted them myself). My sag was minor - the bags look after that fine - if you have considerable sag (the car that is :-0), you'd need expert independent advice I think, because bags, stronger linear springs, or stronger progressive springs and the load levelling hitch would all work one way or 'tuther - an expert (a real one) probably could advise on the best option. Suggestions here may be on the money. I tossed the load levelling hitch idea because I was advised that it needs to be dismantled when you get into low gear, tight-up-down terrain crawling - extensive articulation of the hitch is said to stress the load levelling hardware too much - may break - once rolling again with purpose you maye need to have it all reconnected, unless you can opt to dawdle along for awhile.... and the bags were fine for my "minor sag" anyway.

In my opinion, the first thing to
check is the tow bar height BEFORE you connect the trailer. The trailer hitch could be way out. You can buy replacement hitches to get the right height.
Next thing I would do is to put Polyairs on - They are brilliant and should solve your problem. The standard 100 series
suspension is good and does not necessarily need upgrading. I tow a
Kimberley that has a fairly hefty draw bar weight and although I HAVE upgraded
suspension you will find the Polyairs will do the trick

A set of steel blocks instead of springs will stop the back from sagging.
But they will not transfer the weight back to the front wheels.
In the case of draw bar download the back axle becomes a fulcrum point.
Push down on the towball and the front come up. Simple geometry.
With a sprung vehicle the back will go down first and then the front comes up.
WDH systems correct the problem correctly.
Have a look at the Hayman Reese site for a better explanation.
