F450... as a pick up

So I’m considering trading my 16 F350 single rear wheel in against a similar spec 16 F450. Both have the same mileage.
On paper the 450 is better as I’ll be paying less interest and get an extra year of warranty.
I’ve recently upgraded my trailer to a pre owned tag along trail king w/ tandem duals as my tandem single wheel trailer was constantly on weight limit, as was my F350. I tow occasionally maybe a few times a month, often in or through mountian regions.
Has anyone out there hot or...
