The trailer looks superb! Any details on model and supplier? 😎👍
The trailer was designed by myself (engineering school payback, finally LOL!) as the balance point of the 3-Wheeler is way more at the front than a regular car. This means that if you use a standard car trailer, its axle(s) will be positioned too far back, and the nose of the trailer will overload your towing ball. Both your car and the towing system will suffer.
Then, I designed the trailer and asked several manufacturers (ten to be precise) here in Spain for price and capabilities to do such trailer at a reasoneable price. Seven resplied with a quote, but after clarifications and price negotiation, there was obviously one winner: technically the best one, and the cheaper!!
Price for the trailer 5.832,20 € (21% VAT and all other taxes and fees to get it on the road included). And it has all the features you'll like on your trailer: stabilizer head, two axles of 900kg each, tilting platform, sliding door, hood, tool box, LED back lights, etc.
It's 2.000 mm large, The platform 3500 mm long. The trailer 4750mm total length, and the platform is just at 600m heigh. Total height of the trailer with hood 1800mm. So it fits perfect in a garage. In fact it's the same size as my SUV, so not that big.
I'm happy with it.
