maybe should have chosen my words a little better, forgot what you guys call trailers, we call caravans, two countries separated by a common language eh ! My trailer design is different to most things on the market, so it's not gonna be too easy to copy and hopefully I will go into production with them, so I need to work out some stresses etc for wheel and hitch positions as I dont want to be on the end of any law suits.
The design will have to be down to experience, if it looks right and suck it and see principle then, plus a bit of onroad testing by myself and friends.
