Educate me on all the things I need to know about building a trailer to mount my smoker on. Pics of my intended design attached below. The trailer deck is a bit under 10 feet long and a little under 5 feet wide. Might end up widening it a bit. Other than the total weight of the smoker and utility boxes, etc... What else do I need to know about? I intend to use 15" wheels so that I can easily take it on the highway. It will be towed by my 4WD Tacoma with the tow package. I assume that the whole smoker will be well below the max tow weight of 6,500lbs for my Tacoma. Will a 3,500lbs. axle work for this design? Do you think I can get away with a single axle or will I need tandems for this? What kind of brakes are best?
