Built for
Mid-size construction
An 8-house residential build, frame crew of 8 charging overnight, tool bench and 240 V outlets. Quiet enough for residential noise-zone rules.
Mid festivals
Vendor row at Splore, stage-side at Rhythm & Vines Stage 3, council-approved Auckland NYE. Silent stage power and EV-arrival charging on one chassis.
Dairy support
Comms cabinet, irrigation pump module, frost-fight booster across a 6 ha block, calf-shed top-up over a wet spring.
Hospitality & events
Pair with the espresso & hospitality module — twin-group machine, ~600 coffees a day on solar alone.
Compliance
Tier 2 is transport-engineer certified, NZTA-registered as a Class TD trailer, with a current WoF and CoF where applicable. The electrical stack carries an NZ Electrical Safety Certificate. Tow with a vehicle rated for the gross trailer weight — most utes and SUVs handle a Tier 2.
