Oh ok, thanks. I chose 'trailer' because I found:
"roulotte (n.)
caravana (Portugal), carroça, reboque (Brasil), trailer (Brasil)"
As the target language is Brazilian Portuguese, I chose the *Brasil* entries. Having done an image search, I thought that there were more results for "trailer" that seemed closer to "roulotte"
What do you think?
Also, @ goncin, it says you edited my translation, but I don't know what's changed - could you explain where I went wrong please?
Sorry if I'm being stupid and it's really obvious lol
