How we install our cabinets and other frame works

We add stitching screws every 150 mm to ensure the caravan has full support on all angles. We have pulled apart a lot of caravans and 99% of them only staple the cabinets in through the ply.


New caravans by Quantum deliver supreme quality caravans without breaking the bank. Our passionate team of builders strive to create the best product to your specifications, taking full pride in our caravans with everyone playing their role to deliver perfection. We take no short cuts, we use that extra glue, we use that extra screw, we install that better quality part. We deliver strength, we deliver certainty that your caravan has what is takes to get the job done.

Fully Insulated

We also fully insulate our caravans with 18 mm polystyrene only leaving space for wiring. They are fully insulated walls and roof, top to bottom. A lot of caravans claim to be fully insulated yet when we pull the cladding off you find they only have the insulation half way up the wall and have a lot of gaps.

We see building caravans as an art, the more time you take, the better product will be. We do not slap together our caravans through a production line of inexperienced minds. We take pride in our work, building one caravan at a time, with the whole process taking usually around 2 working weeks. Ensuring our high standards are met and not compromised by restrictions that would see fluctuations in quality.

You take control

Here at Quantum Caravans you are free to express your creativity. We specialize in custom layout and design. From basic caravans for that relaxing weekend away, to family caravans with bunks for the kids, to full off road beasts with all the gadgets to keep you going for months on end. Quantum Caravans are truly aligned to the needs of our customers who are involved in the design process, and are invited to view the caravan during its construction stages. We are always happy to talk to customers about their specific caravan needs to create a product that meets their expectations.
