Давай пробовать.Именно такую работу еще не делал,так что давай вместе пробовать.Так.папка прицепа.Попробуй прописать так:
trailer_vehicle_data: trailer.n.93341
{
model: "/vehicle/trailer_eu/n93341/trailer.pmd"
collision: "/vehicle/trailer_eu/ n93341/trailer.pmc"
rwheel_model: "/vehicle/wheel/steel/rear_single.pmd"

suitable_cargos[]: tv1
suitable_cargos[]: tv2
suitable_cargos[]: tv3

mass: 700

}
Теперь,походу,нам необходимо создать грузы.Создаем  три файла sii.    tv1.sii   tv2.sii    tv3.sii
В них пишем так: cargo_trailer_param: .ttv1
{
trailer: trailer. n.93341
company_look: plain
company_variant: pipes
}

cargo_permanent: cargo.permanent.tv1
{
name: "Телевизоры"

trailer_params[]: . ttv1

fragility: 0.4

price_coef: 0.425
}
cargo_trailer_param: .ttv2
{
trailer: trailer. n.93341
company_look: plain
company_variant: logs
}

cargo_permanent: cargo.permanent.tv2
{
name: "Видео"

trailer_params[]: . ttv2

fragility: 0.4

price_coef: 0.553
can_overweight: true
}
cargo_trailer_param: .ttv3
{
trailer: trailer. n.93341
company_look: plain
company_variant: lumbers
}

cargo_permanent: cargo.permanent.tv3
{
name: "Фото"

trailer_params[]: .ttv3

fragility: 0.3

price_coef: 0.456
can_overweight: true
}
Не забуть прописать грузы в каргосторидж.Как –думаю знаешь.И прицеп пропиши к тем же компаниям,где присутсвует лесовоз(этот момент точно не знаю,может можно и к другим,но так спокойнее.)
