Hi guys,IV just bought a trailer to tow behind my campervan,what is best lining to put on inside bottom of trailer to give it best protection but not sweat or cause rust?

Morning Lance.    My Challenger came with a rubberised box.    Just for added protection I added a rubber mat bought from the trailer supplier.    It's an overkill but helps protect the floor from objects with sharp edges.

Regards

I have a thick rubberlike floor covering  consisting of tiles that fit into each other with lugs. It is an industrial type that is used as workshop floors and supplied by Adendorffs. I dont think it fits your requirement on not causing rust if it gets when as it probably would trap the water underneath  I dont have that problem as I dont transport anything wet. It however does an excellent job of protecting the trailers floor and it is non slip.

Normal house carpet. Easy to take out, easy to clean. Easy to dr.

Good idea. It sounds like ticking all Lance's boxes.

Rubberize hom. Maar kry n plek wat lekker dik laag aanwend

Stem ook vir die rubberise en dan van daai sponserige matte wat inmekaar pas as beskerming van die vloer. 

Ek het my sleepwa ook met daai swart rubberise - 'n dun lagie, oor die hele binne oppervlakte geverf. Die binnekant van die waentjie is baie koeler en hou die koel bokse sommer baie koeler as voor die verf.
