Frequently Asked Questions

Have questions before choosing the Sigma-15? Below are the most common things customers ask us about sleeping capacity, towing, kitchen and bathroom facilities, water storage, off-grid travel, delivery and inspection. If you are comparing the Sigma-15 with the Sigma-13 or other compact caravans, our team can help you choose the right model for your travel style.

The Sigma-15 is designed for customers who want a little more space, comfort and storage than the Sigma-13 while still keeping the caravan compact and practical for touring.

Compared with the Sigma-13, the Sigma-15 is better suited to longer trips, family holidays and travellers who want more room for storage, water capacity and everyday comfort on the road.

Yes. The Sigma-15 is a strong option for longer road trips, family holidays and touring where extra comfort and storage matter.

Its practical layout, sleeping capacity, kitchen facilities, bathroom convenience and water storage make it suitable for customers who want more independence when travelling away from home.

The Sigma-15 can sleep approximately 4–5 people, depending on the final layout and sleeping configuration of the available unit.

This makes it a practical choice for couples, families or small groups who want a compact caravan with enough sleeping space for road trips and holidays.

Yes. The Sigma-15 is designed with practical cooking facilities for touring and camping. Depending on the configuration, it may include both internal and external kitchen options, giving you more flexibility when preparing meals on the road.

This makes the Sigma-15 suitable for family trips, longer holidays and semi off-grid travel where convenience and storage matter.

The right tow vehicle depends on the Sigma-15’s weight, your vehicle’s braked towing capacity, tow ball rating, payload and how much gear you plan to carry.

Before purchasing, you should check your vehicle’s towing specifications and confirm that it is suitable for the caravan. Our team can help you review the key numbers, but final suitability should always be confirmed with your vehicle manufacturer or a qualified towing specialist.

The Sigma-15 is still designed as a compact touring caravan, but it is larger than the Sigma-13 and may require a more capable tow vehicle depending on the loaded weight and travel conditions.

If you are unsure whether your vehicle is suitable, contact us with your vehicle details and we can help you understand the key towing requirements before you buy.

The Sigma-15 can support semi off-grid travel depending on the setup and how you plan to use it. Features such as water storage, greywater capacity and solar support can help make travel away from powered sites more comfortable.

If you plan to camp off-grid regularly, speak with us about your power usage, water needs, cooking habits and travel style so we can help you understand whether the Sigma-15 is the right fit.

The Sigma-15 is designed with larger water storage than many smaller compact caravans, making it more suitable for longer trips and semi off-grid travel.

Please refer to the product specifications on this page for the current fresh water and greywater tank details, as specifications may vary by model and configuration.

The Sigma-15 is a good choice for customers who want more comfort than a smaller compact caravan but do not want the size, weight or cost of a much larger touring caravan.

A larger caravan may offer more internal space, but it can also be heavier, harder to store and more expensive. The Sigma-15 offers a balanced option for families and travellers who want comfort, practicality and value.

Yes. We recommend booking a tour so you can walk through the Sigma-15, check the layout, inspect the finishes, understand the dimensions and compare it with other available models.

Seeing the caravan in person is often the best way to decide whether it suits your family, vehicle and travel plans.

Delivery or pickup depends on stock availability, your location and the final order arrangement.

If the Sigma-15 is currently in stock, delivery or pickup can usually be arranged within 2 weeks, depending on your location, access and order confirmation. If the unit is not in stock, the typical lead time is around 8–10 weeks. This may vary depending on production schedule, customisation requirements and delivery location.

Contact us to confirm current availability, delivery options and the earliest possible handover time.

We provide warranty support and after-sales assistance so you can travel with confidence. Warranty coverage may vary depending on the model, components, usage conditions and maintenance.

Our team can explain what is covered, how to care for your caravan, and what to do if you need support after delivery.
