Gap between bed and doors

[Montlufc]

Hi folks
Has anyone done a mod for the gap at the back of rock n roll bed ? I’m wanting to sit back against the barn doors for watching movies when the bed is down but gap is quite big has anyone got any ideas please ✌

EDIT: Apologies, I misunderstood which gap you were trying to fill!

Visiontech Automotive do a "bed extension" over the nearside wheel-arch, trimmed to match the RnR bed.

This is the best pic I could find...
