2001 Dodge 2500 Cummins TD 4WD 6 speed manual
I could not find or have the time to wait for a Tremor so I bought a similar F-350 Super cab XLT off the lot. It is to carry my 2350 pound Northstar Laredo SC truck camper.
This model has the extra heavy duty suspension made as a tractor to haul/pull a 5th wheel or gooseneck.
It took me a while and a lot of digging to assemble this list of numbers, almost all of which apply to the Tremor, so you might want to copy these specs for your records.
If you find any errors, lehmee noh. As with anything on the internet, you takes your chances.

Congrats on ur purchase, and thanks kindly for posting all the specs for everybody, I also don't have a Tremor, 2020 7.3L F250 FX4. I love.my truck and I know u will also. Nothing like a big block gas with 10 speed with moderate gas mileage to boot.

Stonegrey,
Have you ditched the front air dam yet? I have not looked, but it should be attached with plastic brads and easily removed. There is something hanging down behind the dam that may have to be moved. The 11K pound weight of a loaded hard side truck camper trumps any benefit of the front air dam.
