Wow , I love that " sled " , where do I go to get one ?
Our bike rack is one of those that fits into a bracket on the tow bar with two short pipes on it , and the bike rack slips into that . So we had two pipes the same , welded onto the tailgate . ( spare tyre is up the front )
Also we have two jerry cans on the front sides of the trailer for water . Instead of ever getting a pump of some sort fitted , we just run irrigation pipe back to a tap beside the number plate , and they gravity feed to that .
