To a large extent, it's not that diesel vehicles are heavy, it's that heavy vehicles are diesel, it just reduces the vehicle cost by lowering peak power without sacrificing torque.

I think the price-performance curve is what pushes the weight up on electrics too, minimum cost pushes up engine size which pushes up batteries, chassis, etc.

Then in heavier vehicles, the price drop of diesels makes electric uneconomic again.
