Haven't read all the replies, but remember that those frames under camping trailers are very light. The box on top of it is part of the frame too, as it helps support both ends toward the middle. Usually they are just a 4 inch channel and a few cross pieces of angle. If it were me, I would use the axles and build something stout enough to not have to worry if it were going to be behind me when I got there. The other thing is that you will have to re register it. If you ever get stopped for a light out and they check the registration as a camping trailer with a tractor on it, well, you get the idea
