Why Gun Tractor Shape

[Lang]

Apart from the 18 pounder ring theory (later replaced by a spare tyre carrier)
why did they continue to have the strange shape cutting their potential load and usefulness by 50%.

The same number of people were in the crew regardless of horses or trucks. The riders were all gun crew members just like later gun-truck drivers are also just a member of the crew.

The short wheelbase theory does not explain the sloping back as a square box would hold so much more on the same wheelbase.

I am currently of the opinion it is one of those mindless "we have always done it that way" decisions to continue to produce that shape after the traverse ring storage problem had long passed.
