The Problem: A Factory Option Carries the Converter's Name

A tent sold in a shop is the customer's decision. A tent fitted on the line and sold through the converter's own brochure carries the converter's warranty and its brand.

That changes what has to be proved. The converter needed to know the shell would stay on the roof under a hard braking event, that it would survive a winter of road salt, and that a vehicle fitted with it would still clear the 2.05 m barrier at the airport car park its customers use.

The third point nearly ended the programme. A hard shell tent adds height, and a vehicle that no longer fits an underground garage is a vehicle that loses sales in a city market. Packed height became the controlling dimension, not weight or price.

Why We Chose an Adapted Shell With a Fit Kit Over a Universal Mount, a Ground-Up Design and Dealer Fitting

Supply the standard tent with a universal bracket. Excluded. Universal brackets put the liability on the converter for a joint it did not design, and no engineering team signs that off.

Design a bespoke shell for this vehicle. Excluded. A ground-up programme would have missed the option-list cycle by a year and priced the option out of the market.

Ship tents separately and let dealers fit them. Excluded. Dealer fitting breaks the station time, varies the quality, and loses the converter the margin on the fit.

Adapt the existing aluminium shell to the converter's rail pitch and supply a tested fit kit with installation documentation. Selected. It keeps the tested structure and moves only the interface.

What We Manufactured

The base is an aluminium shell rooftop tent, chosen over a composite shell for packed height and for how it behaves under a static load over years. The pop-up triangle hard shell geometry gives 220 mm closed, which is what cleared the 2.05 m barrier with the van's own roof.

The interface is the part that changed. Rail clamps were made to the converter's pitch, and the fit kit ships as one boxed set with a torque specification and a fitting sequence written for a line fitter rather than for an end user.

The option list also carries a 270 degree side awning on the same rail, so one bracket decision covers two accessories. That is the argument that got the tent onto the list in the first place.

Installation: How the Programme Ran

Sampling ran in two rounds. The first was dimensional: shell to rail, packed height, and whether a fitter could reach the rear clamps with the van's own roof trim in place. The second was structural, and it is the round that took the time.

Fitting was timed on the line with the converter's own crew. Forty-two minutes was the target and the first attempt came in well over it, which is normal; the fix was a change to the clamp sequence rather than to the product.

Installation documentation was written as a one-page card with photographs. The converter's line changes crew, and a document that depends on a verbal handover will not hold the fit time for a year.

Testing and Quality Control

The converter ran its own programme and we supplied shells to it. A deceleration pulse at 8 g with the tent in the closed position and a 75 kg load on the roof, then a 20 km loop on a rough paved surface with the same load.

Corrosion was covered by 480 hours of salt spray exposure on the clamps, hinges and the shell's anodised finish, with the fasteners included rather than excluded. Fasteners are where a rooftop system corrodes first.

Fabric, zips and seals are checked on our side per production lot, and the shell is leak tested before packing. The structural logic behind choosing aluminium over a composite shell is set out in our hard shell rooftop tent note.

Results: What the Numbers Show

The option was listed on both van platforms at the start of the model year, with an internal forecast of 1,400 units a year across the two.

Packed height came in at 220 mm and the fitted vehicle clears the 2.05 m barrier with margin. That single dimension is what made the option commercially viable rather than merely technically possible.

Line fit settled at 42 minutes and has held. Warranty claims on the roof interface in the first season were low enough that the converter has since asked us to quote the awning as a second factory option.

What This Case Means for Your Project

A factory option is a different sale from an accessory. The buyer is an engineering team, and what it wants is evidence tied to its own vehicle rather than a specification sheet.

Tell us your rail pitch, your roof load limit and the clearance your customers actually need, and we will tell you which shell geometry fits before you commit to a programme. Send the drawings to our team and we will come back with a fit proposal and a sampling plan.
