Cheers @GordonHR I ordered the SteeFree complete setup in the end anyway. Having spoke to the boss, we decided that was our best option. It's our first time of trying to use a dayvan so we thought we'll see how much we use it before splashing out on something like a slidepod.I've just thought... the only reason I need an extra layer was because my hip was on a solid wooden board. My head was at the tailgate end. You probably wouldn't need it if you slept the other way
