well hummm i think it could be a tight squeeze on a 4x6, if u think a standard truck bed is liek 6' long, my foreman fits inside the bed of my truck with the tailgate down but i dont pull it completly up to the rear window cuz i have a piece for my tonneau cover up there that gets in the way but when i strap it down my tires are still completely in the bed of the truck and not on the tailgate
hope that kinda helps...if u have a gate on the back of the trailer id say it wouldnt fit but you could try
