Hiya mate,
I have something very similar to what your looking for. It is tow ball mounted and holds 4 bikes if i rememeber right. I can't remember the make but its very similar to what your after. It is currently packed away in my garage here in birmingham. It could be posted but im guessing this will be quite expensive due to size. I can take it out over the weekend and send a pic if you like? I'm looking for about £50 ish ono
