Hi there!
My name is Tom and I live in Poland. Last month I started building my small caravan trailer. One peculiar thing about this trailer is that it will be a kind of the box that fits inside ordinary utility trailer and can be installed or removed when necessary.
I am using OSB board for the floor and something called MFP board for walls and ceilling. MFP is also a wood-based board, much harder, more durable, water and moisture resistant than OSB. It is also much heavier, so I made a lot of holes in order to make the whole thing lighter.
At the moment I am fitting the outside shell- PVC panels.
Will share some photos with you so to show you my idea. Hope you like it.
Sorry for my English, it is not my native language so if I am not understendable, please ask for better explanation.
Glad to join your community,
Tom
