I think there shouldnt be a limit for how many tents/deployables you have, or at least it should be bigger then 16. If you think about it those who can place the tents bought the dlc and therefore they should be limited with the amount of how many they can place.
Tents should cost the same as now so 16,000 or maybe even more if you could have more then 16 and it would be like an "end game" where if you buy an expensive tent it would it would take some time to get the money for it. But it shouldnt grow on price with each tent you buy.
