how to join multiple rovemates for big rovers?

They should be surface attachable, if they are not then you will need something in between them.

Cubic octagonal struts?

I suggest dithcing the rovemates altogether - I find them cumbersome and hard to put stuff on. If you want a good rover base, I'd suggest just using the structual girders of plates.

Should be surface attachable, like Taki117 said.

It's worth mentioning that a rover doesn't have to include Rovemates at all. For example...

This is the Hellhound 7, my most successful rover design. Designed this puppy waaaaay back in 0.19 and it's still the one I go to for big jobs, despite the changes in part designs over the years (I only wish the 88-88 antenna was that small these days). At its core is a OKTO2 attached to a Reaction Wheel (it was called a SAS Module back then), with Structural plates below that. That's a key element of rover design IMHO - you got to encase the crucial bits in parts with high impact tolerances (panels and girders). If you don't, you risk having a catastrophic accident if (when) the rover flips over.

Remember - build them low, build them wide, SAS on, drive in Docking Mode. Keep the critical bits encased.
