The Owner's Insights on the FREUCAMP Under Bunk Air Conditioner
This one goes under the bunk instead of on the roof, and that's the whole reason to buy it. Nothing on top means no extra height, no drag and no hole cut through your ceiling.
It's reverse cycle, so the same box does 2,200W of cooling in February and 2,200W of heat pump plus a 500W PTC element in July. Three vents spread the air around rather than blasting one corner of the van.
Two numbers to check before you order. It's 734 x 398 x 296mm, so measure the space under your bunk properly. And it's 28kg, which is weight going into your van, not onto the roof, which is better for your tow ball but still counts against payload.
Why You'll Love the FREUCAMP Under Bunk Air Conditioner
- Fits under the bunk. No roof hole, no extra height, no wind drag.
- 2,200W cooling and heating. Reverse cycle, so it's cool in summer and warm in winter.
- 500W PTC heater as well. Extra heat on a genuinely cold morning.
- Three vents. Air spread through your van instead of one cold corner.
- 300 cubic metres an hour. Enough airflow to turn a van over properly.
- Three fan speeds. Wind it back at night so you can sleep under it.
- Runs on 240V. 820W cooling, 1,260W heating, so 3.8 to 5.5 amps.
- One-piece EPP frame. Insulated and simple to fit, fewer parts to fail.

Why under bunk instead of on the roof
A rooftop unit means cutting a hole in your ceiling, adding 250mm or so of height, and carrying 40-odd kilos up top where it affects how the van tows. This one lives in the storage space under your bunk. No hole in the roof, no extra height under a carport or a low branch, and the weight sits low in the van where it belongs. What you give up is the storage space it occupies, so decide which you'd rather have.
Measure the space before you order
It's 734mm long, 398mm wide and 296mm high, and that's the hole it needs. Under-bunk storage varies enormously between vans, so get a tape measure in there before you buy rather than after. You also need to allow for the ducting to the three vents and a return air path, which an installer will work out with you. Ring the store on 03 7056 6732 if you want to talk it through first.
What reverse cycle actually gives you
It's the same refrigeration circuit running backwards. In cooling it pulls 2,200W of heat out of your van. In heating it puts 2,200W back in, and there's a 500W PTC element on top of that for when it's genuinely cold outside. It's rated to work down to -7 degrees. Below that a diesel heater is the better tool, but for the mornings most Australian travellers actually see, this covers it.
What it draws, and what that means off-grid
820W cooling and 1,260W heating on 240V, which is 3.8 to 5.5 amps. On a powered site that's nothing. Off-grid through an inverter it's a genuine load: running it for a few hours needs a decent battery bank and a station that can hold 1,260W continuously. Add up your setup before you count on it, or look at the power station range if you're building that side of it.
Getting it installed
The one-piece EPP frame makes the physical fit simpler than most, but this is still a 240V appliance being built into a vehicle with ducting and a return air path. Get a caravan fitter or an auto electrician who does this regularly. The install manual is on this page and covers the dimensions and requirements. Call the store on 03 7056 6732 and we'll talk you through what's involved.
What's Included
- FREUCAMP under bunk air conditioner
- Remote control
- Installation manual
What's Not Included
- Professional installation
- Ducting and vent kit for your van's layout

The unit and the remote are what you get. Ducting, vents and the 240V connection are all part of the install and depend on your van's layout, so talk to your fitter about what yours needs.
Not Sure Which Under Bunk Air Conditioner Suits You?
The FREUCAMP under bunk suits you if you want reverse cycle air conditioning without cutting your roof, and you can spare the storage space under the bunk. It's the wrong pick if that space is already spoken for, or if you'd rather keep the storage and take the roof height, where a rooftop unit is the answer. Not sure if it fits your van? Call the store on 03 7056 6732, or send an SMS to 0476 330 590 and we'll check the measurements with you.
