I don't think there is a problem with an imported trailer.. The thing is steel..steel can be welded and fixed relatively easy.
The tent would be my concern. A) the size.. Having it up a massive tent, couple of drinks or not, it's a pain in the arse. B) quality of said tent for waterproofing ability. If it leaks, your going to be wet and pissed off.
Nothing like a good base to build up from though. As others have mentioned, you can get a good second hand for this money, that will have any bugs ironed out of it.
Good luck, enjoy the camping.
