# 4WD and touring builds: payload, plates and proof

> Touring 4WD builds accumulate GVM upgrades, suspension lifts, bar work and accessories — most of which affect legality, payload and insurance. ModVault records each modification with its certification status and keeps the evidence producible when it counts.

## Why 4WDs get scrutinised

A touring build changes ride height, mass, braking demand and frontal impact behaviour, often all at once, and then gets loaded to its limit and driven a long way from home. That combination attracts attention at roadside inspections and at claim time.

## GVM upgrades are a paperwork exercise as much as a hardware one

A GVM upgrade is either a federal second stage manufacture approval or a state certifier route, and the difference matters for how and where it is recognised. Keep the approval documentation, the compliance plate details and the suspension specification together — the upgrade is worth nothing at a weighbridge or a claim if you cannot produce it.

## The accessories add up

- Suspension lift — certification depends on height and jurisdiction
- Bull bars and bar work — ADR compliance and airbag compatibility
- Wheels and tyres — placard diameter and track limits
- Long-range tanks, drawers, canopies — real payload consumption
- Dual battery, lighting, comms — ADR compliance and correct aim

## Remote travel makes offline access non-negotiable

The inspections that matter for touring vehicles happen a very long way from reliable coverage. Your records need to be on the device.

## Frequently asked questions

### Does a GVM upgrade need certification?

Yes. A GVM upgrade proceeds either through federal second stage manufacture or a state certifier route, and the approval documentation must be retained.

### How much can I lift a 4WD without engineering?

Allowable lift without certification depends on the jurisdiction and the vehicle. Basic changes within specified limits may not require certification; beyond those limits, certification under VSB14 section LS applies.
