I haven't got one for sale, sorry, and apologies for if this is an "egg sucking" reply, but, I purchased an 8ft single axle trailer many many years ago , which has proved to be very useful and easily manoevred due to it's single rather than double axle.
If I was in the market for a small trailer, I would defintely look for a single rather than double axle trailer
I have refloored it twice, had to repair the tailgate hinges, fitted stock gates and also a rear support leg, but it's much easier to use than more modern ones
