I have a question for those who have designed and/or built a TTT. I have seen at least one TTT that was built on the Harbor Freight trailer, but the floor was extended to either side such that the wheels were underneath the trailer vs. on the outside.
Do you need the chassis to have supports that extend to the outer edge of the wheels to accomplish this, or can you accomplish it with the floor structure, using the standard 'box' of the Harbor Freight (other other manuf.) trailer?
Hopefully my question makes sense.
