Re: The Towing thread

Depends. If you're going to use the car off road or getting it dirty, I believe it's important in the long term that all the electrical connections are made inside the cabin. Many installations are achieved by tapping into the vehicle lighting harness under the car. It doesn't matter how much tape is applied... this will cause problems down the track. This might not matter if it's a "town car" and you're just towing a 6x4 to the tip twice a year, but if not perhaps enquire how the electrical works will be executed?

FWIW my recollection of the cheapest I got quoted was $650 for Hayman Reese with no supplementary trailer lighting interface box.

It's also worth considering if you plan to have a brake controller and power fitted, as these are best done at the same time.

Cheers,
Steve

Thanks for your response - I was thinking of getting an auto electrician to do the power / anderson plug etc after the towbar so sounds like I might be best to get it all done at same time. It will be used for towing CT, I hadn't even thought of connecting all wiring inside the cabin. Appreciate your help.

Re: The Towing thread

Just get the towbar installed would be my advice in this context. You probably won't save much, but your car's wiring will not suffer at the hands of some three toothed, beanie wearing spanner monkey.

Cheers,
Steve

I'm not sure this is entirely true. The point of LT's is to have a tyre that is firstly, stiff to allow loading and off-loading without out the need to constantly change tyre pressure and secondly, less bouncy to stop the typical high centre of gravity truck swaying too much. In other words, they are not intended to run bulged. The sidewalls are quite stiff and will generate more heat than a passenger tyre with thin bulgy sidewalls designed for comfort. For this reason LT's have a lower load carrying capacity for a given tyre pressure. Nevertheless, They are certainly tough and I have no hesitation taking them down to 18psi but I am aware of their limitations.

Re: The Towing thread

This is a question, not a post follow. Can you wire up reversing lights from GC 2015 to caravan that is already wired. One Auto Elec bloke said no cause car has live wires on that system?

Re: The Towing thread

I wired reverse on mine so it is definitely possible. I grabbed the reverse feed from just behind the right wheel arch inside the boot, before it passes up the rear pillar and into the tailgate. The details are in my DIY Trailer Wiring thread.

Depending on the wattage of your reverse lights, you might need to use a relay to avoid overloading the reverse light system.

Cheers,
Steve

Re: The Towing thread

Just got back from towing my Jayco camper up to Shark Bay, and I was impressed with how the V6 petrol GC handled it.

The only issue was with cruise control on hills, but the few there were just meant dropping out of cruise for a big stab of the pedal, to drop 3 cogs or so..

It's handy being able to see oil and transmission temps in the cluster!

Re: The Towing thread

Hi folks. First post here. I did a search, well, a few of them. But no definitive answers to my question.

I'm about to buy a Grand Cherokee Limited CRD. It has 20" tyres. I was told that I should've opted for the 18" ones as they are better suited to towing heavy trailer loads. In our case it will be a caravan weighing around 2,300kg.

The dealer is fitting the towpack as its described in the contract. I'm assuming that it will be rated to 3,500kg. But I'm going to have to check back with the dealer on this.

But getting back to the tyre option. Should I have asked to the 18" option? The vehicle will do mostly sealed road work with some unsealed but mostly smooth dirt roads. No going off road.

Thanks

Martin

The Towing thread

Test drove both before buying, found the ride noticeably less harsh on 18's (steel suspension) than the 20's (quadralift)
18's better if you're planning to go offroad IMHO

Edit: 20s look much better though!

Cheers, Simon

The GC that we're looking at doesn't have quadralift. I believe that's either an option or standard on models higher than the Limited which is what we're getting.

And it won't be going off road. If I was going to do that I'd have bought either a Prado or a Hilux.

Re: The Towing thread

Martin, as per my post on Whirlpool, 20s vs 18s have NOTHING to do with the tow rating. Make that decision based on other desires - looks, off road, replacement cost, ride quality and handling etc... but tow rating is not something to consider. Whoever made that comment is waaaaaaay off the mark.
