Hitch a trailer in career mode.

Hello,
I'm in career mode and I would like to hitch a trailer. I guess the car needs to be equipped with a hitch. How do I add it when it doesn't have one. I have the ETK 2400i.

Also, I bought the Gavril H-Series but in "My vehicles", it says "Not owner!". Below it says Purchase (3,225.00) but I don't have enough money and it's grayed out. The only valid buttons are "Repair" and "Sell".
Thanks
The traffic is really annoying. They stop for no reason on the roads.

 

Okay, I understand for my Gavril H-Series. We need insurance which costs 3,225.00 B. But for the trailer?

 

for the trailer, go into the purchase parts menu, find the tow bar in that list and install it (like you would have done with the rear spoiler in the tutorial).
then, back the car up to the trailer, press L, and once it's close enough they will "magnetise" together and attach.

 

Thank you very much! I couldn't find it because this part of the game is not translated.

 

Hello,
I'm getting back to you because although I have a hitch, I still can't have a trailer. What does lvl3 or lvl4 mean?
Thanks

 

the level required to do trailer missions, for example if your only level 2, you cannot do the trailer deliveries, if your level 3 and above you can do trailer deliveries.

 

Ah OK! Thanks
