I will be transporting a 2 x 2 x 4 foot item in my pickup truck. The dimensions are approximate. It is an old heavy printing press and the weight has been estimated at 700 pounds. The plan made by the owner is to lay it on its side in the truck after removing a handle on the down side. This item is top heavy. My idea, since it has to be unloaded, it to place a board across the bed of the truck (there are slots on both sides for this right above the wheel wells). Then under this board put concrete blocks. Then lay the printing press down, lean it actually, onto this supported board.
I would put it as close to the front of the bed as possible, right behind the cab, so as to try to get the majority of the weight as close to the center of the 4 wheels of the truck. I'll have to do some travelling on the interstate highway.
Physics wise, will this cargo affect the stability of the truck at high speeds?
I do not want a fish tailing vehicle.
I lifted one end on the printing press off the ground and I am age 55 and weigh 160 pounds. It is heavy but I don't think it weighs the estimated 700 pounds. I hope to be able to travel at least 55-60 mph and want to know if this cargo and the way it will be carried will affect stability of the truck in any way.
