Offroad Grits Water Catcher Explained!

Not only allowing more roof space for solar, our premium rear spoiler has an integrated rain catcher

How Our Caravan's Rear Spoiler Doubles as a Smart Water Catcher

When most people see the large, aggressive rear spoiler on an Offroad Grit caravan, they think it’s just for looks — a tough finishing touch that adds a bit of flair. And while it definitely looks the part, the spoiler is much more than a styling accessory. It’s a clever, practical solution designed to help you stay off-grid longer: it doubles as a smart water-catchment system.

Here’s how it works:

Angled for Water Collection

The rear spoiler is carefully angled to catch rainwater as it flows off the roof. Instead of letting that precious water splash off and go to waste, the spoiler channels it towards the outer edges, where it enters integrated drain pipes.

Drain Pipes on Both Sides

From the edges of the spoiler, the water is fed into drain pipes that run down both sides of the van. These aren’t your average caravan gutters — they’re built into the design and made for serious remote touring. Whether you’re camped in the bush or on the coast, a quick downpour becomes an opportunity to top up.

Bucket Collection Made Easy

At the bottom of each drain pipe is a removable bung, which allows you to collect the rainwater straight into a bucket. It’s simple, low-tech, and works anywhere — perfect for washing up, cleaning gear, or topping up your water supply when off-grid.

Optional Filtration & Pump System

Want to take it to the next level? You can option in our rear toolbox setup, which connects the catchment system to a filtration and pump system. That means you can filter the rainwater and pump it directly back into your main tanks — giving you more time off-grid and fewer worries about running dry.

Built-In Stedi Work Lights

And because we never miss a chance to be practical, the spoiler also includes integrated Stedi work lights — lighting up your rear setup area at night, whether you're collecting water, reversing into camp, or just enjoying the view.

More Roof Space for Solar

One of the added bonuses of relocating the aircon to a ducted system and integrating rear design features like the spoiler is more usable roof space for solar. That means larger solar arrays, more charging capacity, and better off-grid performance.
