Not one bit. If you have to go over Ratan Pass, (not seeing the route I don't know if you will) use your lower gears. Denver is about an hour and a half from Cheyenne on I-25, !-80 connects there. You've got this!! I have total faith in you!This is a rough outline of the route AAA gave me: head west to TX getting close to Dallas, go north and get close to Denver, then get up to I80 and go across WY til I get there.
I told them about pulling a trailer for the first time and the agent tried to keep me out of big cities and off mountains.
Does anything seem out of whack with that route?
