Byronic
flares don't stick out as much as wing mirrors. if they protrude 50mm and that is filled with insulation , you still gain the extra width of the wall thickness, 2-4 inches each side. or just don't put wall panelling and insulation where your head and feet need to go , just fix carpet or camping mat to the van skin to stop condensation
I pull my wing mirrors in if needs be, distance then is within the wheelarch width.
Truth is bulges look terrible in my eyes. I'm just trying hard to find a practical
justification for not having them!
Wm. Morris "Have nothing that you do not know to be useful or believe to be
beautiful". That's what he quoted, of a stately home or old nail of a van!
