Hi
Towed a caravan to Ukraine and back in 2001. Did not stay on any recognised Ukranian caravan sites, in fact did not see any!
Went as far as Chernigov, which is about 100km north of Kiev. On entire trip stayed at proper site only once, that was in Poland on the way back. Went with a group, some of whom had been before, and don't think I would not go as a single unit. The roads at the time were very poor - in fact the old military road from the Polish border at Chelm to Kiev was awful and virtually shook the caravan to bits.
