Can I use this mismatched panel effectively with my current system?

The current setup on our RV is 4x JJN 100W panels (ground deployed) running in parallel. https://www.amazon.com/gp/product/B09V558GBJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
Vmp 20.4v
Imp 4.91a

I have an opportunity to get a Furrion 370w panel for free, and would like to mount it on the roof of the rig. https://lci-support-doc.s3.amazonaws.com/furrion _off the grid/ccd-0005520.pdf
Vmp 34.2v
Imp 10.82a

Charge controller is a EPEVER MPPT 40a: https://www.amazon.com/gp/product/B07KT9F38P/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

I'm thinking I can go two groups of 2S with the 100w panels, but my brain starts to break when I try to figure out how to integrate them with the 370w panel. Would I simply run all of them in parallel for best efficiency? So 200w 24v + 200w 24v + 370w 24v (the 370w panel would be relegated to running 24 v?) Is there a better way of making this work (including adding an additional panel?)
