I noticed that when i bought the van last week the side step wasn’t fitting properly. I found that I needed a deep step because of the ply board so I bought one. However, I’m still having problems fitting it. I’m assuming that it is because of the bit of board circled in blue.
Is this what is stopping the step to fit properly? Shall I chop it??
