Truck is a Nismo Frontier with a class 4 hitch. I have towed stuff a lot heavier than the busa before no problem, no suspension mods needed. I thought this thread died already, kinda surprised to see it back up. Still leaning toward building a trailer as there is no U-haul location where I will be to "one-way" the trailer at, and after 7-10 days of renting I might as well buy one. Building one will let me get exactly what I want and I get to keep it too.
