At first i've been reading the whole internet for inspiration and how-to's. I've found the website of the Wyoming Woody ans i liked the shape of it. Only i want a mattress of 200cm and that doesn't fit in the plans. I scaled everything 10% up and than it will fit.
At the same time i looked for a suitable trailer. In Europe you can't buy trailers like Northern Tool is selling.
I've found an empty caravan-chassis from the brand ALKO (most used in Europe) just 30 kilometers from our house and it only cost me 50 EURO. Got the trailer and parked it in my garden where the build is gonna have place.
Trailer is with brakes and total weight can be 1000 kilogram, i hope the teardrop is not gonna be that heavy.
