Thank you 2gypsies, star dreamer, VC 23RSS and Ray for your valuable input and advises. appreciated!
2gypsies! Thanks for such detailed info on the roads and grades. I think of sticking to I-90 route
Star Dreamer! We are planning to leave by the end of this month, i.e. September, so hopefully will not encounter the snow/ice
VC 23RSS! I have F-150 4WD SuperCrew V8, 5.4, 6 gear transmission and has additional transmission cooling add up for pulling. Trailer brakes are good (so far!) but are not disc and are electric drum brakes, and probably going by night is not a bad idea for me ( if wife allows😉!)
Yup Ray! it's a decision time! 😃
