3/4 ton payload vs. towing capacity

I just upgraded from an F250 V10 gasser to an F350 diesel. It is night and day. I towed through the mountains and the diesel did not scream like the gasser. Yeah, the gasser could handle it but seeing it hit 5000 rpms and higher and hearing it sound like the pistons were going to come through the hood. Diesel never went about 2500 rpms and it did not downshift that much. Most of the time it dropped to 5th gear and a couple times down to 4th. The one ton diesel really took a lot of the stress away...in fact, the first day of the trip I drove 935 miles in 19 hours...stopping for fuel, food, bathroom breaks and leg stretching. Get the 350/3500.
