My issue with the rovers is, it sounds to me they intend to introduce a third class of weapons between personal and ship for vehicles, and shields that are smaller than ships' shields as well, so no matter how beasty a rover, an Aurora LN or an Avenger could very easily put it down. If you're familiar with the history of armored personnel carriers you know they're bullet magnets and if they can't stop incoming fire, all they do is give opponents a target to shoot at.
I'd much prefer to use an Avenger for short haul transports on the surface, and fly it with either the Tigerstreik or even a Mantis. On a close support craft, that Mantis would be nasty. Probably we will never see a rover that can take a hit from that and survive. The issue is that the rover is carried by the Carrack, but it still looks like an Avenger will fit in the Carrack's bay and if you have an Avenger aboard you should be able to swap out combat crew carrying capacity with the EMP Generator. Those two should make great additions to the Carrack's bag of tricks.
If you really think you'll need surface transport, throw a couple Dragonflies aboard. Just remember, soldiers on foot will always be harder to hit than vehicles, so the only reason to have a vehicle is if it can stop incoming fire, and they probably can't stop any ships' weapons.
