Leethal, Were there any difficulties getting your home made trailer through inspection to get it registered? Engineering reports for load ratings etc....
Pete, as long as you have the important bits covered like tyre, spring and coupling ratings, stamped load rated safety chain, adequate lights and reflectors, wheels covered with mudgaurds and flaps etc, it is not going to be hard...
But, I have friend who is a trailer builder and he checked it out and was very happy that it was up to it's 250kg gross weight task. It is registered as 'homemade' with one of his VIN's on it. It never went to be inspected... like i said, no-one here cares...
The bike towbar, well, who knows... only a cop on a bad day might have a grizzle and i'll wait and see for that one!
