Xpedition ADV Northstar Excessive cab heat

[ultmax]

We have a new xpedition northstar and looking for suggestions on reducing cab heat. After 40 minutes of driving in warm weather the heat coming up from around the seats becomes too much. We have a/c but that’s just not enough to compensate for it.
We only see an external heat shield or interior insulation as a fix. Has anyone had any success with either? Thanks!

Heat is coming from the radiator.

I have been trying to find a way to divert the heat to the side,s.
