Coromal indepentant suspenion

Sorry forgot mention that its towed behind a 4wd wagon.

You may be able to change the coils to air bags, make it easier to get more height. You may be able to put poly air bags in the original coils, not sure if the coils are big enough for the poly's. Any have a talk to people who make air bag inp susp. Mob in Brisbane called Vehicle Components might be worth a phone call.

What model Coromal is it.
I have a Princeton with "independant" suspension which is actually only two sets of axles with leaf springs as in two completely seperate sets.

Whilst is independant of each other it is no way the same as say a Jayco setup which has the springs connected via a swivel arm and thereby makes them "helper" springs.
Is your rig level when set up on the car or have you got the towball too high and the rear sags
Depending on how far you want to lift it you could alter the handling considerably by lifting it too far.

The cheapest way would be to get two heavy boards and pack the low area where you reverse in. Much less trouble than altering supension.

I had to get mine realigned and without a lot of work it cost Coromal $900.

Markus,
coromal suspension is excellent so I would hesitate changing it.

Gotta ask is the van level on the back of the wagon or do you need a dropped tow hitch.

Options you could employ are fit larger wheels/tyres when negotiating the driveway, place something down to take the slope out or modify the suspension.

To raise the suspension it would have to be engineered and could be done by removing the suspension and then installing a 50mm high sub frame with the original suspension mounted on that.

Have a good one

I had a Viscount Supreme some years ago and that had two small wheels under the back end to stop the caravan from bottoming out.

Markcus,
If your caravan is only giving you grief when you are backing up YOUR driveway and nowhere else, why bother changing it with suspension modifications.

Your problem could be solved by changing your drawbar tongue to one with another 50-75mm more drop just for backing up the driveway. Use your normal one for towing.

OK its a bit fiddly having to change it over each time you come in or out of the drive, BUT it does not change the caravan set up in any way either, which can be a good thing too.

IT's probably the cheapest and easiest option.

Hope this helps you solve your problem

Disco.

hi markcus
is it at all possible to put in a culvet/pipe type drive way to permantly eliminate the drain problem
could be cheaper than altering the suspension
or have some steel cross overs made that can stay there for ever
that being subject to council rulings of course
cheers
