The Role of Vehicles

[Cdnwolf]

Finally got the infantry rules done for Roll20.net and now working on vehicle rules and was wondering how people see the role of vehicles in the Escape From Kalisz and other modules?

How much vehicle combat did your groups ever use. (besides using the secondary armament to mow down attacking troops?)

How much effect did LAW and RPG have on your vehicles?

In combat did you have to unhitch a trailer and fight or went into combat with the thing still attached?

Thanks for your feedback.
