Almost cross-country trip

[Mono2]

Hey all-
Looking for advice, opinions, ideas, cheats etc regarding do’s and dont’s of driving from OH to WA with my MM 2108DS. Currently I do NOT have an anti sway bar and she rolls pretty true on the dozen or so 2-3 hour trips I’ve taken.
Pulling with a 2018 GMC Sierra 5.3 ltr. V8.
Thinking about mid October and probably 70 to 80 then to 90 interstates.
I’ve made many drives across the US both in cars and tractor trailers with the military (on taxpayer’s dime).
Hoping to do this trip within 14 to 16 days, spending 4/5 days anchored in Tacoma at the in-laws.
Any advice is greatly appreciated.

Biggest thing for us what getting in mind how early winter comes in the Northern but far more important if the higher elevations. Mid october is going pretty far into the off season/ freezing time for much of that route, so be prepped and aware. Not that it can't be done but much colder much sooner than Central Ohio, so takes some thought. Look at campgrounds closed dates for sure? Some stop taking reservations after SEpt 30 and some will not have water due to freezing.
If you have the "tow/haul" option for downshifting on the truck, knowing what to expect from it is good as you will meet far different hills than might be the normal---or you may have already done that on travels!
Just a headsup to be aware?
