Is this Australia's stealthiest camper?

We've spied some stealthy campervans and motorhomes over the years, but this one takes the cake!

Residing in NSW and based on an Isuzu NLR 200 light truck, it looks like any old delivery or work truck on the road, and wouldn't get a second glance with its plain black side curtains and aluminium rear roller door.

However, looks can be very deceiving, with the inside of this box truck boasting a very tidy campervan/ tiny home-style fit-out that includes cooking, sleeping, showering and toileting facilities, not to mention hot water, power and storage solutions.

Nicknamed Frank the Tank and currently listed for sale on caravancampingsales at $99,000, the stealth truck camper has served as a relatively cheap and hassle-free, home-away-from-home for the past couple years.

"Sick of paying rent? So were we," the seller says in the description.

"We lived in Frank the Tank for 2.5 years in perfect comfort and parked anywhere we liked without issue while we saved to buy a house. No rent, no bills. Travelling? It's a lot cheaper when you don't have to stay in caravan parks!"

"Order click and collect groceries and put them straight in the fridge. Simple."

As can be seen from the photos (and walk-through video) in the listing, the internal make-over is a sight for sore eyes for any RV traveller on a tight budget.

Lifting the rear roller-door reveals a timber-lined porch incorporating a compost toilet and hot/cold shower, as well as some stylish fake tiling and timber cladding.

Enter through the house-style door, and there's an east-west double bed that lifts up to provide seating for up to six people, as well as some sliding windows previously hidden behind the side curtains.

The internal fit-out also features a timber work station, wardrobe and drawers, a skylight, and a chef-ready kitchen with two sinks, slide-out prep board and induction and gas cooktops, a spice rack, and fridge/freezer.

For off-grid power there's a generator and a 300Ah lithium battery system with 2000W inverter and 400W rooftop and 300W portable solar panels. There's even a 'garage" behind the curtain outside for tools, toys and outdoor gear, plus external floodlights and a safety camera.

"It's a very comfortable little space and very stealthy, never once has anyone questioned us," the seller says in a walk-through video.

"We have a Google map of many places you can stay around NSW, where taps are to refill the water tanks etc."

In case you were wondering, the three-berth, 4500kg GVM truck camper has clocked up around 300,000km and comes with service and parts replacement records, as well as an engineers certificate for the motorhome conversion.
