The F450 pickup is not a popular vehicle with savvy LTL commercial haulers. Then add crew cab 4x4 on top of that and he has a very heavy truck with low money making payloads. He simply has a white elephant for that type work.
His rear axle problems are not the norm. Anyone can spend some time looking for a youtube to show a particular slant on any brand or size of truck or whatever the agenda requires. and is not a bash on the OP. Just stating facts.
Hell I got 180k-200k miles from my all of my '70/'80s 460/454 one ton DRW Fords and GM trucks hauling 26k-32k combined and never had internal gear damage like he is having. Sure we changed out a few rear axle bearings but nothing major.
Its rather amusing listening to RV folks telling the industry which size vehicle they should be using. I tried the HDT for moving my materials/equipment from docks to work sites. Very expensive lesson learned the hard way in the first 6 months.
There are several reasons a one ton DRW truck is still a top money maker in the business. And on the flip side there are good reasons a MDT/HDT doesn't work the best.
