Flat:
The basic Sankey is much too small to live inside, but with the extensions we put on it gets to a length where you can do something with it. It only has 1500kg gross weight, so you can't go too mad, but we think Philip's version will come out OK.
Brown:
The non-90 deg bends will be done by cutting the cant rails at an angle, no pre-made bits unfortunately.
The push-in square tube fittings are great for knocking up interior fittings, cupboards etc, haven't used them myself but have seen lots of examples.
With the experience of building the big 6-wheel drawbar trailer, this is simpler but where the drawbar trailer was a design and build, the chassis being drawn up first followed by the body, the Sankey has to fit around a pre-existing base, and we modified that as well before the body was started.
Nothing I'd change really, it has worked out OK, possibly the top slope down at the front might get ditched as the compound angle is going to be awkward on the cant rails.
We have cancelled our regular trip to Holland and France in May/June next year so we can get the Sankey and the Mercedes both finished. A trip to North-west France is planned, so the cancelled Stena Line monery paid for the Britanny Ferries crossing from Portsmouth to Caen and back in September.
