Right i'm almost ready to start looking for a sankey trailer i was looking at fitting an 88" roof but now decided against it as since my last post we have bought a mig welder and son has learn't to weld so now looking getting one fairly cheap sorting any welding out and making it into how i want it, looking for a wide track as it has better brakes.
Now my question is if i was to get one and go to collect it i only have a tow ball on the S2a 88" but could fit a ball and pin type hitch just get it home and sort a pinickle hitch later, would this work just to get the trailer home
