Miles per day

I am heading from Nebraska to the Eastern Side of the Adirondack Mountains. I have 3 weeks with nothing I plan to see in between. I route across I80 to 80/90 to 90, take a short cut, then I87. It is about 1400 miles. I have pulled this far before but with a smaller TT. I typically stop at a truck stop every 150 miles to check everything and rest. I certainly appreciate the input from everyone.
