My issue is not so much with high RPMs as the tranny wanting to shift up and down, which causes the transmission temp to go up. I need to remember that I have to ability to manually downshift to keep it in one gear.
As for payload I know the truck don't care about an extra 200 pounds. I used the TH since this a RV forum, but I also have a licensed catering trailer that weighs pretty close to the same. Being licensed in Kansas makes it a commercial vehicle meaning I'm subject to DOT laws. I would guess the chances of me getting weighed are not that great, but if I did THEN the extra 200# just might matter.
