I agree, you should be able to get info online. Another idea, is go to some area dealerships and look at actual trucks. They will have door panel stickers with actual ratings for the given truck.
IMO, you will need a 350/3500 SRW diesel, as a minimum. With nearly 40' length, a DRW would likely be the better tool. If you don't want DRW, look closely at SRW ratings, payload, axles, and max tire ratings.

The problem with just checking the door stickers is that most dealer stock have the lower gvw. Dealers rather have flash on the floor to sell than utility.
