Historically Jeeps were THE plow vehicle through the 50s/60s/70s, and beyond.
It's only in the last 30 or so years that most plow duty has been picked up by heavier 4WD pick-up trucks.
Certainly plowing was hard on Jeeps, and many suffered damage from overuse/under-maintenance.
Today's Jeeps are heavier with stronger frames than the early Jeeps. Jeeps still make a good plow vehicle, but require more skill/finesse than plowing with a heavy truck.
