My customers are requesting the type of trailer in the link.
It is a Dragon 130 barrel vacuum trailer used in the oil and gas industry. On page 3 of the pdf there are specifications for the over all design. More specs can be produced as needed. Wheel and tires will not need to be drawn as I have a source for rubber tire and wheels I want to use. There are couple detail on the real model that are not necessary on the 3D model but I will clear that up.
Looking for a 60 day turn around. This will take much material, hollow parts are necessary.
