The Story Behind Mountain Chassis

Based in Campbellfield, Victoria and owner-operated since 2017 — here’s how Mountain Chassis got here, and who’s actually building your chassis.

How We Started

Mountain Chassis has been building bespoke caravan chassis and custom trailers from our Campbellfield workshop since 2017.

Baljinder Singh owns and runs Mountain Chassis today, and he’s still hands-on in the workshop every day, on the tools alongside the team. That direct, on-the-floor ownership is at the heart of how we work: the person who quotes your build is the same person building it.

What Mountain Chassis Looks Like Today

Today, Mountain Chassis is an efficient, quality-conscious team based at our workshop at 2/19 Dennis Street, Campbellfield — in the same industrial corridor as many of Melbourne’s established caravan manufacturers. We specialise in:

We work with caravan manufacturers running production orders, custom van and owner-builders working on one-off projects, private buyers commissioning their first custom chassis, and trades needing suspension or coupling work. Whoever you are, you deal with the same workshop from your first phone call through to delivery.

Our Workshop

Mountain Chassis operates from a fully equipped fabrication workshop in Campbellfield, Melbourne. All cutting, forming, jigging, welding, and finishing capability is done under one roof, built to handle both production runs and one-off custom builds.

We’re set up to work from your own engineering drawings and tolerances if you’re a caravan manufacturer, or to guide the specification from scratch if this is your first custom build.

Why Owner-Operated Matters

There’s no off-the-shelf range at Mountain Chassis, and there’s no layer of sales staff or account managers between you and the person doing the welding. Every chassis starts with a conversation about your build, your load, and where you’re actually going, and the person having that conversation with you is the same person who’ll be fabricating it.

For a first-time private buyer who’s never ordered a custom chassis before, that means no jargon and no pressure; we’ll guide you through what you need to know. For a caravan manufacturer running production, it means a direct line to the workshop floor.

About Us

Why Choose Mountain Chassis

Bespoke, not off-the-shelf

At Mountain Chassis, there is no standard range to choose from. Every chassis starts with a conversation about your build, your load, and where you’re actually going.

Owner-operated, direct communication

No sales desk, no account manager. You deal directly with the workshop from the first call to delivery — fewer mix-ups, no re-explaining your build to someone new, and answers from the person who actually knows your job.

Built for real Australian conditions

Every chassis and trailer is fabricated from Australian steel, built for real Australian roads and conditions — daily touring through to serious off-road and remote travel.

One workshop, every stage

Chassis, trailers, suspension, coupling and repairs, all from the same Campbellfield team. No juggling separate suppliers or re-explaining your build to someone new, just a seamless process from enquiry to delivery.

Precision and compliance you can verify

Flatness, squareness, and straightness are checked on every chassis before it leaves the workshop — not assumed, verified.

Compliance you can rely on

Structural welding to AS/NZS 1554 standards and ADR 62-compliant drawbars, with engineering certification arranged where a build requires it.

Backed by a 3-year warranty

Everything we build is covered for 3 years, so you’re not just taking our word for the quality.

Honest quotes, realistic timelines

Clear, itemised quotes and straight answers on timing — no hidden costs, no surprise extras, no overpromising on lead times we can’t hit.
