Every opening in an off-road caravan shell — hatch, vent, window, door — is cut before the panels go on. That makes ventilation and glazing specification decisions rather than accessories: the roof has to carry the hatch, the air conditioner and the solar array without one blocking another, and rework after loading is paid for by the importer. Settle both on the drawing.

Roof space is a shared resource

The roof is smaller than it looks: the air conditioner, solar panels and hatch compete for the same flat area. On a model that documents roof-mounted air conditioning, the hatch still has to open fully and be reachable from inside, so ask for the roof plan of the exact model, with every appliance and panel position marked. The published custom off-road caravans range lists roof-mounted air conditioning with a heat pump on the 21ft model and puts the air conditioner on the options line for the 16ft hard-tops, so the roof layout follows the build rather than the model name.

Ventilation is a system, not one opening: a hatch or roof vent extracting over the galley, plus opening glazing on both sides, is what removes cooking moisture from a small interior.

Glazing: acrylic, glass, single or double

The 21ft off-road caravan with double acrylic glazed windows documents that specification, and acrylic is common on off-road builds for good reasons: it is lighter than glass and tolerates the flex and stone impact of rough roads. It also scratches, and years of strong sun dull the surface, so a spare pane is worth holding.

Glass resists scratching better and is often easier to replace locally, at the cost of weight and a greater chance of cracking on corrugated roads. Double glazing keeps the inner pane warmer and reduces the condensation that runs down single glazing in cold weather. Tint level, and whether every window is double or only the main ones, belongs in the specification — specifications vary by model and final configuration.

Screens, blinds and the parts that fail

Flyscreens and blockout blinds appear on a build sheet only when they are ordered, so confirm them window by window instead of treating them as a range feature. What fails first is rarely the glazing: seals harden, the stays holding a wind-out window lose pressure, latches and hinges work loose, and screen mesh tears. On a hire fleet those are everyday repairs, which is why a first spare order should carry seal profiles, stays, latches and screen panels. Those same seals are the usual entry point for water and dust, so a replacement set belongs with the units, not in a later shipment.

What to put in the order file

Five lines settle most of it:

• The roof layout — hatch and vent positions against the air conditioner and solar panels, with clearance noted.
• The glazing schedule — pane type, tint, opening style and position, per model.
• Screens and blinds — confirmed window by window, including the mesh specification.
• Wear parts with references — seals, stays, latches and screen panels, listed against supplier part numbers.
• Transit protection — glazing protected for the voyage and inspected before shipment, plus one written line per model confirming the specification.

The 21ft model documents double acrylic glazed windows and a 3,500 kg GTM, and the 16ft hard-top models are rated to a 3,000 kg ATM, so openings change with the options ordered rather than with the model name. Send the models you are considering and the climate they will be sold into — hatch, glazing and screen details can be confirmed against the drawings before the shell is closed.
