I have 2014 off road double cab. I have no custom mods. Driving at 75 is intolerable. I have to turn the radio to like 40. I have been reading through threads here . My question is probably addressed but what is the best bang for the buck to quiet it down some? I just want to make it tolerable e.g. radio on maybe 30 at 75. Is there a recommended minimalist work e.g. the doors? Spay underside or do I have to rip out everything to make enough difference? I really want to quiet it down, but not enough to tear everything apart.
