Now not needed -this did have the humber 3.4 RIB on it which fitted with ease so can easily take sibs and RIB up to maybe 3.6 or 3.8 ish if they were not to heavy. I would think an ideal medium size SIB trailer.
Got a winch fitted and new hitch and I've had the wheels and hubs off to give it a once over so all is good .
