When I get to my real PC, I will transfer all this stuff to a new thread for you, PS. It will just get lost here ...

Weight distribution is the key. Moving stuff around changes my ball weight from over 80 kgs to between 40-50 kgs.

I have towed my fully loaded 7x4 box trailer at up to 130 kmh behind my '93 Impreza (1800 cc) and my 1400 cc 1981 Colt! Tens of thousands of kilometers ...

If yours is an auto, probably worth checking out tranny coolers, if not already fitted.

Towing at the speed limit is not even noticeable in Roo2. My trailer fully loaded is (just) less than 750 kgs.

Yes my outback is an auto (cvt) and I did look up installing a trany cooler although Subaru Australia does say no need to do so. Might ask a famous subaru mechanic in perth to install it if decided to go ahead with it.

We plan to load the trailer evenly and our biggest concern is the fridge if we decided to get one.

Some Subies came standard with tranny coolers, or do not need them.

Really depends on whether you plan to do the Gunbarrel Highway, or something similarly ridiculous ...

BTW, I took the liberty of adding your full size images to your OP.
Hope you don't mind?

Default UAT - User Acceptance Test

Ok, gave the trailer and the battery systems a test over the long weekend just passed. All good except the leaking water systems and we have taken it back to the vendor to have it fixed under warranty.

All in all, the trailer does the job and we are happy with it particular with its own kitchen!

The battery got fully charged and with all the LED lighting we didn't bother re-charging the battery at all.

The only thing not sure is the rear of the car seems a bit lowered when hitched to the trailer and we don't think it is due to the tow ball weight as it also happens when the trailer is empty. Any idea to rectify this?

We were thinking whether the Mchitch RatBag recommends would help fixing this or not?

Gidday PS

Sounds like shagged self levelling struts to me, mate ... ... but your car looks too new to have this problem. Seems to show up at 100-200K kms.

First, check that you have SLS (canisters on the front of the strut).

Second, measure your tow ball weight (or jockey wheel weight, the latter being about 80-90% of the tow ball weight). Ideally, should be around 60-70 kgs, loaded. Redistribute load to achieve this ball weight.

Third, measure your wheel centre to top of wheel arch with nothing extra in the car and without trailer. Height should be within OEM spec .

Fourth, hitch trailer and re-measure. With trailer attached, rear suspension height should only change marginally (I.e. -10 to -15 mm). You will have to drive car and trailer a few kms to allow the SLS to pump up, if it's going to.

If you still have bad sag (saggy butt syndrome), replace the SLS struts with non-SLS units, as I had to do.

McHitch make fantastic products, IMO, but fitting one will not fix your rear suspension if it's shagged.

the standard suspension is just too soft, any sort of weight outside the wheelbase makes them sag.
then take into account the actual mass of the towbar (50kg) plus any tools or gear you're carrying inside the boot, then drp 100kg+ of camper weight on it.

the SLS units are supposed to work with the extra weight and push the struts upwards to level it out, but it takes a few bumps to begin working.

Personally, bin the factory suspension all together, fit some KYB struts and Pedders Springs

Thanks RatBag and Rob for the feedbacks...

Will check the towball weight etc when I get the trailer back; and start from there.
