Mostly correct.
But consider this; how much would the infantry travel on roads? Let's assume a road speed of only 50 km/h. A five-hour move would certainly be an exception for infantry, happening only once in some weeks. The average truck might be moving less than one or two hours per day (logistics vehicles would move much more).
That's 22-23 hours per day without movement (albeit possibly waiting on or next to a road). Do you want a huge protected but difficult-to-conceal truck (an invitation to concentrate the squad in the vehicle especially in cold climate) or a smaller, easily concealed vehicle?

Concealed vehicles wouldn't need to be guarded as much and the lower weight and fuel consumption reduce maintenance and logistical requirements.
Some off-road capability is required for many tasks. Engineering vehicles for earthworks and lower echelon supply vehicles as well as vehicles for ATGM or mortar crews need to be off-road capable.

Furthermore; the armour employed in MRAPs is not quantity production material. Even if they used simple RHA we would still have a supply shortage in the event of a major war that requires ten thousands, not only about 2,000 vehicles per year. What's our equipment good for if you cannot produce it in wartime quantities, if you cannot equip your mobilized army?


Israel is a special case. It has rather high force densities in the event of a war, hard ground surfaces in many areas, many hilly terrains (Negev, Sinai, Lebanon, Golan) that don't permit much off-road activity anyway and its possible opponents cannot expect to achieve much with their reconnaissance or artillery.
