@Onychorhynchus coronatus
The use of vehicles as decorative items in exhibits is weird and not something I am a big fan of. I have however noticed that animals often use them as a form of enrichment, for example as look-out points or sleeping areas (and I saw the dholes at Zie-Zoo doing both). That said I would still prefer something more naturals like rocks, logs, wooden structures or hills with dens to achieve that purpose.
Also, the stickers on the vehicle were texts relating to a dhole conservation project in their native range, thus tenuously linking the exhibit to the native range and the conservation of the species.
@Onychorhynchus coronatus yes, definitely, I bet it would maybe fit if it was outside the exhibit, just to show that it was thematic, but without giving this weird unnatural look... at least it's a big exhibit, actually it has a very nice size; these animals have the opportunity to walk around a lot in there...
