It’s a good idea to keep the water as low as possible. This reduces your centre of gravity, and decreases the chance of your vehicle falling over. This is something to bear in mind when considering adding any 4×4 Accessories – a high centre of gravity is never something that you want! It’s worth keeping your water in several different containers if possible. A popular option is to have one large tank on the underneath of your vehicle, but what happens if a stick or rock puts a hole in it? By having a backup when it comes to water storage you won’t run into any trouble.
It also pays to think about how you are going to measure the water left. Whats the point of a massive 100 litre tank if you can’t tell how much is left? A gauge is well worth getting, as well as a reliable pump. What happens if your electric one fails? Do you have a way of easily getting the water out? Some of the cheapest systems for water storage include several 20 litre water jerry cans plumbed together. You can do this for under a few hundred dollars, and you have a system that can be made to fit almost anywhere. Poly and stainless steel tanks are also favored, but they do tend to cost more!
One of the main issues when travelling is the lack of space. Being able to make use of every single location in your vehicle or trailer to carry what you need is extremely important. I have seen custom made tanks that sit in between the vehicles body and the rock sliders, or even in the rear quarter panels. Wherever there is room available, make use of it, as it is hard to come by when you are preparing for a big trip!
