Re the weight issue - grab your melways (or equivilant street directory) and look up your nearest public weighbridge. Most trucking yards or scrap metal yards will have one you can use for free (or a small nominal fee) that will give you an idea of what kind of weight your towing.
Sounds like a larger car might be on the cards soon though ...

Argh... you lost me a bit there Komodo!

OK so I think the foolproof option is more for us! We only really would use the 1 car to tow this I think.

Spoke to auto electrician and I think I successfully confused the poor man. Here's what I think might work for us.

1 x 100AH battery, think this will be mounted in a box in our boot, it can then be charged while we go out for the day etc. When we return we can remove it and plug it back into the fridge. I guess we need a smaller battery to run the fridge while we are out???
The auto electrician said $190 to wire the car and $195 for a 100AH deep cycle battery.

I wish there was a caravan and camping show on!!!

Funny you should say that about the weighbridge, we were wondering if we were allowed to use it, there is one on the way up to Newcaslte I think.

The trailer was custom built, it's all aluminium so it's really light, I can push it around the yard. It's the stuff we have put in it!! Plus we worry a bit about the positioning of all the weighty things, we kind of try and keep it balanced.

$195 for a 100aH battery is cheap - mind you I havent priced them up recently I only know what I pay for the batteries in our scissor lifts so I took a punt a pricing.

What your suggesting sounds like a good idea to me. Definately the small battery to run the fridge whilst your away in the car is a good idea (maybe look at a RAPS for that).

Good idea Gypsylady, we have one quite close.

I thought I found what we needed....

Its a bit more than just a battery box but I do agree it is about $350 - $400 more than it should be (and even then OL would be making a reasonable profit)

Out of interest I went to Independant Battery Distributors today and priced up batteries (100AH)
$190 for lead acid - fine for a trailer. Needs ventilation so cant be in the boot of a car. Charges fast

$360ish (cant remember exact figures) basic sealed battery. No maintenance. can be installed in car.
$390ish - bees knees sealed battery supposedly.

Repco had basic battery boxes to suit these batteries for $26.99.



Im interested in this topic because I am putting together a camping (not camper) trailer myself at the moment so I'm looking to change to lead acid batteries (200AH - $390) and a 240watt (3x80watt) solar setup (should provide more than enough power even on the more over cast days.)

Good info Detective Komodo :)

So the $390 battery is that 100AH or 200AH? Didn't realise the ventilation was an issue, is that for overheating reasons? I keep coming back to the weight issue though unfortunately.

I was at work today and checked what auto electrician they use, so will give them a call, probabaly not till early next week. (Darn work constantly gets in the way of my holiday planning!!)

I will have a look for the battery box at Repco sounds good.

There was two for $390
One was IBDs top of the line 100AH sealed unit (suitable for in cabin)
the second was a 200AH lead acid battery - probably the option I will go for. Im not fussed about weight (the patrol actually goes better when dragging more weight because it loads the turbo sooner so it spools faster - unfortunately this has the adverse effect of using more fuel though).

Where are you putting the battery in the camper?
The more centralised over the trailer axle the less you will notice the weight. Unfortunately you cant get a light weight battery - theres nothing available (nor do i think its possible) as all batteries use lead - more lead = more capacity = more weight.
Seriously though 30kgs (typical weight of a 100AH battery) is only the weight of the average 7yr old. Its a one man lift.

Why is weight the big issue? is it because of towing capacity? fuel consumption? vehicles ability to climb hills with the additional weight?
braking ability? does the trailer "push" the towing vehicle on decents? if so perhaps (electric)trailer brakes might be an option?
Im assuming being a little 1.6L (petrol?) engine that its front wheel drive ?
front wheel drives actually tow quite well typically and if its auto the torque multiplication done by the torque converter should allow it to pull like a steam train provided the wheels can sustain the traction. Obviously you can achive a similar result with a manual - but you'll have very little clutch left by the end of the trip LOL

Other than that the only thing i can suggest is stripping weight else where if you want to run the fridge you'll need a battery. Battery = weight. Its unavoidable unfortunately.
Reading your earlier posts you talked about taking a camp oven. I hope your talking about a spun steel unit not a cast iron one?! a cast iron camp oven will weight nearly half the weight of the battery - and I know which I'd be leaving behind (as much as I love it) and it wouldnt be the fridge and battery!
How much gas are you taking? not a 4.5 or 9kg bottle I hope? I take a 2kg bottle and that'll last me well over a week camping (I'd guess 2.5 weeks) - including using it for cooking and light.
How much water are you taking - 1L water = 1kg. Now im not saying to skimp on water but work on 5L per person per day with no other water access. if you have access to other water ie a river or tank etc then look to cut that back to about 3L per person per day - 7 days 3 people = 63L. Most CTs have 80L water tanks so simply by filling it 3/4 instead of full you stave nearly 20kgs
You also spoke of taking a shower and shower tent. Personally I'd take the shower and leave the tent at home. You can shower out in the open in the bush - or if you want privacy a small tarp tied between a few trees does the trick and weighs bugger all or less.

What does your setup consist of? Obviously you have a camper trailer so your not lugging a tent what are the main "weight" items?

I had a dual battery system installed in my Subaru Liberty for about $450 all up. I sourced a second hand 3yo 80 amp hour AGM battery that had been taken out of a UPS system and had the installation done for about $350 with an auto electrician. The battery sits in a battery box with two 12v ciggy sockets in the boot of the car and powers the fridge nicely for a couple of days before needing to turn on the engine to charge it up a bit. I don't think the guy I bought the battery off has been able to source any recently though.

Careful with used UPS batteries. Sometimes they are a bargin sometimes they are not.

I bought a few a few years back and they were brilliant. Later on a mate and I went in together and bought about 10 for a solar project. Only about 4 of the batteries were any good but because they were bought "as is" there was no warranty. As such we would have been better off buying 6 brand new batteries for the price we paid for the 10... Hind sight.
