This is the way it's done in France. No need for big 4x4s or a trailer,just a Twingo. This guy designs and builds his own boards. There are some great pics of him building them in his living room. Obviously not married. The designs are a bit different too. Colas might know more.

That's cool mon!

Look fine........until the little car starts to take off

You need to see some of the pics from DJ's 'zook' years. Multiple (big) boards plus a fat bike in a box on top of the Suzuki Swift, bound for the mambo.
