Front and back panels were made next, I can mostly describe these as being a 'total twat'
The shape of the Transit does not lend itself to making easy templates, it took me a good 3 hours to make the template for the front panel, measuring, trimming, swearing, starting again and then eventually transferring it to the ply for the front end. This would be trimmed on the outer and plastic backed on the inner.
Have another pic!

And carpeted
Believe it or not this piece of wood took 8 hours of my life! and I think that was the easier of the two panels, this one being carpeted, the rear one would be made from the same ply as the front panel so had to be pretttyyyy good. And no, the template from the front didn't suit the rear :-(
Rear panel, another half a day!

Trial fitted with ply fitted to the sides of the van and insulated, all ready for trimming.
And finally side wall carpeted, the joint between roof drape and side wall carpet would be inside the N/S locker as originally planned.
Bed top out and in countless times, along with many other things to fit bathroom/water heater etc but in eventually. Trial and error an understatement!
