As some of you don't know that I own a mazda double cabin 98 model (which is toyotafied with 3L engine by previous owner), the vehicle in question is also my daily commute as aswell. Now as the summer is approaching, i'm beginning to worry about the cabin cooling. I have acquaintances with d-cabins of different age and gender and to be honest the AC in these things is not impressive despite having 'huge' engines.
Anyways, what i wanna know is how to improve the cooling of of d-cabin so that I can enjoy the ride even in hot summer days.
2ndly, the other option is to increase the insulation of cabin, what can be and should be done about it and from where.
