I'd like a tipping trailer, that one is like almost 10' long and 5'6" wide, that's huge.
It gives a loading height but doesn't actually say how high the sides are so you can figure out cubic capacity.
I have an 8x5 with high sides and it cubes out to almost 4m3
Mines not a tipper and emptying it can suck if you slashed a load down. Tippers almost double in weight over conventional trailers as you need a chasis plus another whole frame for the trailer/tipper part. That one at almost 1tonne empty would need a large 4wd like Landcruiser or truck pulling it I'd say. Think my little Bravo 4cyl would be struggling.
Nice trailers they build, only criticism I have is from experience I'd have the higher sides solid on the sides and mesh front and back. That way when driving empty wind can pass through but when tipping nothing gets stuck in the mesh on the sides. Maybe some 1.2mm sheet should suffice with all bracing being on the outside so you have a smooth inside for stuff to slide out.
Other benefits are when you leave the tip the wind cleans out the tray and the roadside gets mulched.
Plus nice flat surface for sign writing.
