Hi all

I’m planning to custom-make a water tank for my Nissan Patrol GU and the dimensions are as follows:

Length 950 mm
Height 530 mm
Width (Up 200 mm) & (Down 350 mm)

It holds 135 liters and will be placed behind the middle seat.

Please note that it has only one baffle and the baffle’s dimensions are as follows:

Height 450 mm
(Water tank height is 530 mm)
Width 200 mm down & 100 mm up
(water tank width 350 mm down & 200 mm up)
Length 130 mm
(water tanks length 950 mm)
Please note that the length of the baffle is not an important factor,
as far as I know, since it plays no role to reduce the water slopping around.

My mate at the water tank shop told me that the baffle has to be hollow, because he will make the tank from Polyethylene. Since the baffle is hollow, I will lose about 9 liters. That’s why I have to make only one baffle to reduce the amount of liters lost by making the baffles.

So what you guys think about having only one baffle in the above-mentioned tank? Is one baffle enough for my tank to prevent or at least minimize water from slopping around?

Replies are highly appreciated.

Many thanks.

I think that one baffle should be enough. More would have been better but at least this way the water shouldn't slop around too much when you are cresting those big dunes.

Hi there Saudi Camper, I had one in the bcak of my lux up against head board and held 170 Litres. It was the full width across bar about 2 inches either side so I could get to brackets to bolt up and was about 45cm in depth and 1cm down from the top edge of ute well. Was made out of aluminium and had an outlet dead smack at the bottom in the middle with a hole drilled through the ute well floor and a rubber hose with a ball valve at the end screwed to my rear step bar worked a treat. Not sure how Im going to set up prado yet maybe the same but like yourself with the tank inside behind seats. I didnt have any baffles in myn at all as it was just a try out to start with and was going to make a stainless one up but cause the aluminium one turned out how I wanted I didnt bother making a stainless one and not having any baffles didnt seem yo make any difference as far as rocking from side to side, Maybe with coil springs might be more noticeable I'm not sure. I think one would be ample for yours. Regards Steve M

Saudi Camper, putting a baffle in shouldn't reduce your tank capacity appreciably if being hollow, you make sure it actually allows water to get in and out of it. Allows it to fill and empty with the rest of the water in the tank.

Have a water tank on the back of a vehicle and it definitely destabilizes it with water slopping around without the baffle in place.

I have a 60 litre tank on the chassis of my Nissan. Just watch your weights with one so big.
