CO HWY 82 from i-70 to Aspen, CO

No problems. Biggest issue we find is the stop lights don't seem to be very synchronized so can be lots of getting up to speed only to slow back down. Not steep at any point. I don't know where you're heading in Aspen with a TT, but parking is pretty limited for a vehicle with a trailer. Difficult CG would be the only choice I could suggest right around Aspen. There are a couple of CG's up Lincoln Gulch but they are first come, first served, busy, and up a somewhat rough gravel road. There are a couple of CG's up Maroon Creek that will fit the smallest of RVs and trailers but they book quick.
