I can't add much to what the esteemed members have already stated except for 3 small tidbits of personal perspective:
- Grew up hauling all sorts of stuff on whatever truck would go and hopefully stop, also hauled all sorts of stuff with the old station wagon with steel bumpers and a big block.
- Will still do the above ^^^ as needed, but if given a choice, I prefer to be within the published ratings of vehicles. Trucks don't magically blow up if one goes over a rating, but just as personal preference I like to stay in said ratings.
- in 2019, bought a new F250 (diesel, CC, 6.5' box). Used it for tows under and over the ratings, nice truck, absolutely no complaints. At the time, the same truck with F350 badging and rating was on the lot for $1,200 more. It was black vs. my preferred slate grey.
Point: I think the OP would be OK with a modern high-spec "3/4 ton" / 25 series. That being said, since 2019, I've had a small twinge of regret over not spending the extra $1,200 and getting (however ephemeral) the extra rating of the F350. If the OP is able to get a modern high-spec SRW 35 series truck for a relatively nominal $ increase, I'd suggest going that route.
