My rear cupboard in my van doesnt fit and is very loose. so I pulled it out and have brought a sheet of MDF to make a new one but I am stumped as to how to meausre the profile of my Sheldon Hightop. To explain what i am trying to do a little clearer I want to cut the MDF to fit exactly right across the van but the hightop has a very intricate profile. Once done I will cut a hole in it and put a door on it.
So has anyone done this before? or is there any techniques which I could use to cut this wood


Cheers
