This looks like it was pretty much a standard van, with the interior fitted out to accommodate foam cans and foam making induction equipment and branches.
These did not have enormous carrying capacity, despite the high roof, so the amount of kit on board would have been rather limited. But the design did offer plenty of headroom for any one loading or unloading it.
