A gullwing hatch for the Troopy

Considering most of it was overseen from 6,000 miles away, the modifications to our 1993 Troop Carrier significantly exceeded our expectations. Mostly.

The Mulgo pop top conversion, installed at the Expedition Centre in Sydney before we ever saw the vehicle, was exactly what we wanted. Full standing headroom, a full-size drop-down bed, excellent ventilation. The roof was strong enough to walk on, and the modification added just two inches to the Troopy’s stock height. A 100-watt solar panel (which I later upgraded to 200 watts) provided power to the auxiliary battery for the fridge, lights, etc., and a bracket held a pair of MaxTrax.

The extensive internal plywood cabinetry, which Roseann had designed and a provider to the Expedition Centre had built from CAD plans, worked out just as we’d hoped. We still haven’t run out of storage space.

However. As a reasonably proficient carpenter, I was less than satisfied with the quality of the plywood, which appeared to be a better grade of standard five-ply big-box-hardware-outlet stuff. Worse, though, were the numerous nail and screw holes, which had been filled in with badly contrasting white wood putty, even on drawer fronts. Some day I plan to pull the entire unit out and replicate it in Baltic birch, with dovetailed drawers and invisible fasteners. But for now, as I mentioned, it’s perfectly functional.

One spot, though, is worse than the rest. The back of the tall sink cabinet backs up against the big front rear window on the driver’s (i.e. right) side—and it is peppered with nail and screw holes that aren’t even spaced consistently. It made me cringe every time I walked past it.

Ug. Ly.

Fortunately I came up with a solution that was both aesthetically pleasing and practical as well.

There is a bit of clearance between the back of the cabinet and the glass, varying between one and a half and two and a half inches. The plywood offered a tempting place to mount things such as a hatchet, Silky saw, and jack components. And Graham Jackson had recently sent me a link to the German company Explore Glazing, which makes extremely high-quality glass and aluminum gullwing hatches for 70-Series Land Cruisers, as well as for Jeeps, Land Rovers, G-Wagens, and, recently, the Ineos Grenadier. I got back with Graham and we each ordered one—I of course specified solid aluminum to better hide that wood work, even though the glass versions are quite dark.

Graham and I were both impressed with the quality of the hatches when they arrived. He installed his first, and his emails saved me some extra work.

The first task is to remove the factory window, which is not difficult. The hardest part is getting all the butyl sealant off, and I found that Gorilla tape worked very well to peel it off cleanly. Then comes the violent bit: The vertical lips of the 70 Series factory window opening are slightly curved, and the hatch frame is flat. So you need to use something like a short section of 2x4 and a small sledge to pound the edges of the frame reasonably flat. It take some real force (and wincing) since the sheet metal there is doubled. Once that’s done you can line up the hatch frame to drill the mounting holes. The frame uses a thick foam gasket as a seal, so if you haven’t got the window from perfectly flat it won’t matter.

I ran into one issue that was unique to our situation: The very nice pop-out latches of the Explore hatch ran into the back of the cabinet. So I had to drill and cut out two little rectangular holes in the cabinet for clearance. Access for tools was limited, so the openings are not as neat as they could be. I console myself with the thought that they match the rest of the “woodwork.”

With everything in place you can mount the dual hydraulic struts, which hold the hatch open firmly, even in a strong wind. At this point the hatch is usable and, according to the company, “99.9 percent waterproof.” However, they include a tube of Dow Corning 721 with which to caulk around the perimeter of the frame, thus completely sealing it and adding a finished look as well. The instructions say to apply the sealant, then brush the excess with a soap and water solution to remove it. But an email from Graham said, “Don’t do it! It just makes a mess.” So I simply applied the bead very carefully (using a zero-drip caulking gun) to be flush with the edge of the hatch frame, and cleaned the excess with a razor and scrubbing pad once it had cured.

To say I’m happy with the result would be an understatement. No longer do I have to look the other way when I walk past that window. And there was enough area on the cabinet to mount a hatchet, a Silky saw, the Troopy’s jack extensions, and a breaker bar mounted with the correct 21mm socket for the vehicle’s wheel nuts. There’s actually still a bit of space to consider.

If you don’t have an ugly cabinet to cover up, there are at least a couple of alternative functions for the Explore gullwing. If you like the idea of having a few tools quickly available behind the hatch, the company has an optional molle panel that provides ample opportunities for attaching odds and ends. Or, of course, you can simply use the hatch to access items in the interior of the vehicle without the need to open the rear doors and swingaways. One friend with a Troopy installed his fridge where it can be accessed either from the interior when camped with the roof up, or through the hatch for lunches or drinks.

The Explore Glazing hatch is expensive (around $500 plus shipping), but the quality is impeccable.
