I have procured a large lot of aluminum. My uncle just happens to be a fabricator and I have access to the shop and tools at night and evenings. He is going to help me so that I don't screw up too badly and we are building a 6 hole trailer with UTV storage. I've had some axles lying around for a year or two and finally found a deal on some aluminum. For any of you who have a trailer / box or have built one...what are considerations for ensuring an exhaust fan pulls hot air from all compartments? The last thing I want to do is build a structurally sound box and trailer and then have ventilation problems. We won't have any problems with the construction, but neither of us have ever owned or used a trailer like these so we are a little hesitant about whether we should use an air space between all the holes? Insulation?
Thanks in advance!
