I do plan on towing the smoker about 3 hours away to my grandmas house for thanksgiving so i might consider a tandem. They really aren't that much more expensive, they just interfere more with getting to the cook chamber. Thats my biggest hurdle at this point. I am using the standard 10%-15% tongue weight rule and it seems no matter how i design it, the wheel falls at the back half of the CC (which makes sense since the smoker is the majority of the weight of the trailer assembly). I am working on trying to move the smoker over so that the wheel is somewhat tucked under/beside the smoker.Big T wrote: ↑September 3rd, 2020, 6:27 pmI don't think that a tandem axle is a must have for a smoker of this size as long as you don't start adding a lot of things to the trailer. There have been plenty of them built on single axle trailers over the years without any issues. If you were going to be pulling it long distances on a regular basis a tandem axle would probably be the way to go because I think it would ride a lot smoother. My 24 X 48 with a WC is on a single 3500lb axle and it bounces pretty bad when going over bridges at high speed which puts quite a load on the springs. I believe that Frank has replaced the springs on Mack 2 or 3 times and it's on a single 3500lb axle. As for your 2nd question, I've seen several smokers built on the forum that were offset and I only recall one person having any problems. His trailer leaned to the heavy side because of the load on the leaf spring. I believe that he put the next size spring on that side and it corrected the problem. If you check out the Mack build I believe that there are some good pictures of the trailer build on the thread.
