Travel in eu will always be deciding factor on buying a trailer or not i thinkI see where you are coming from however now i have swopped cars i have to swap my trailer too as the aygo wont fit as its longer so next trailer will have to be 12ft minimum to make your theory work that also means im entering the larger / heavier world of trailers
and yes i do need an A frame Uk. and a trailer too EU
So if you need to get a larger trailer are you selling the small one you can no longer use
