Silversun Neptune 402D: Review
Lightweight and feature packed, the Silversun Neptune 402D is a force to be reckoned with.
Silversun is a small Brisbane-based RV manufacturer that has been a successful van/bus to motorhome converter for some years and has recently moved into caravan manufacture.
DESIGN & CONSTRUCTION
So what about the positives? For a start, the Neptune’s DuraGal chassis is built along conventional lines with 100x50mm (4x2in) main rails and drawbar and 50x50mm (2x2in) RHS sections for the cross members. Although it’s made with DuraGal steel, the chassis has a Hammertone paint finish.
The Neptune is fitted with simple leaf spring suspension. Given the adoption of a few European techniques in the construction of this van and its super lightweight, I had almost expected to see the torsion-style suspension fitted to many British and European caravans.
The drawbar is fitted out with a ball coupling, handbrake, swing-away jockey wheel and single 9kg gas cylinder. Instead of a front boot, there is a large alloy checkerplate box and it offers plenty of external storage space, including a shelf for small items.
To keep weight down, fibreglass composite panels are used for the overall body construction. The end result is a pretty ‘square’ looking van, at least from the rear, but the front is more streamlined. A short Omnistor awning covers the entry door area, Dometic windows are fitted all-round and the security door is an Aussie Traveller.
Although the Neptune is quite a small van, Silversun has taken the liberty of fitting a slide-out barbecue to the front nearside. I particularly like this addition as it provides an alternative cooking source with the benefit of reducing cooking smells in the relatively confined interior.
For a small caravan, the Neptune is well-equipped in the utilities department and has a 100L water tank, a Duetto 10L 240V/12V water heater, a 120Ah deep-cycle battery and a 200W solar panel. Although not really designed for remote camping, it’s pretty well set up for this purpose.
As you might imagine, towing this van is a breeze. Having an unladen ball weight of only 60kg makes it ideal for any number of vehicles, including the Hyundai i40 wagon we used for our test, which coped without any trouble at all. Since the Neptune has an ATM of just 1290kg, it fits well within the Hyundai’s towing capacity.
