How To Install Trailers?

[Coxster]

How do I install trailers like the 'mega_tesco' one? I place it in the makes\trailers folder, load 18WoSPTTM and go into the showroom. I click mega_tesco and it pops up without wheels and then the game crashes. Do I need to install anything else? There are no instructions included.

Ive got a mega trailer, that uses some of the defualt wheels from the game. I can send u that if u want. Otherwise, in the mega_tesco trailer, open the description.def file and where it says wheelrx, change that to wheelr0.
