There are a few rare cases where you have to look at vehicle carry costs when you select units, Canada I think is one.
The Bison has a larger carry capacity than the Lav so you can buy what you like but for the others unless you need to look at the units your buying. HMG & EryxAT wont fit but take the MMG or the Carl Gustav team & they will.
Never seen it as an issue
