I was looking at pictures of the 2018 Caracal and noticed the forward compartments have vents and my 2015 Caracal does not. Did a search here and did not find a post about it. What is the purpose of the vent system-heat displacement, condensation control? Is the vent system something that could be added? If not, what measures could I employ to offset the effects that warranted the vent system? Thank you.
