Standardize on a light tank (recce) then a medium tank (Panzer IV or Panther).
Medium with a long-barrelled 75mm could defeat all WALLIED and most Soviet tanks. Tigers were a huge waste of resources.
Captured factories (e.g. Czech) should focus on building light tanks, artillery tractors, etc. to German patterns.
Yes, standardizing trucks would also help. Start by standardizing common spare parts like tires, brakes, spark plugs, distributors, etc. Bodies can be specialized for different roles (general cargo, liquid cargo, ammo, radio, etc.).
