Hi. Greetings from Argentina.
My name is Santiago and I own a Hilux 2016 dual cab.
First of all I apologize for my writing, my English is not good.
I work with dogs and at this moment the box (stretcher) of the truck is closed with a fiberglass canopy, which takes away the possibility of carrying loads. And because in this country there is nothing similar to what you know as UTE TRAYS. I am starting the project in CAD to build an aluminum tray myself.
The tray will be 180 x 180 mm although if the regulations of my country allow it I would like to take it to the 205 mm long that would be the length with the bumper.
Now, my specific question, since I am starting the design, is. What diameters and thickness do you use for the structural aluminum of the tray? I am sorry to use 70 x 40 x 3 mm for the 4 perimeter and 2 central, with 50 x 20 x 3 mm for the transverse. What do you think?
I would appreciate any photo or diagram of the structure.
Thank you very much and again, sorry for the inconvenience of having to understand me.
