We're heading to Estes in a couple weeks with our travel trailer and possibly Grand Lake the following week. I'm hesitant to head over any large passes because of it's my Yukon's age and powertrain. It did well hauling the camper to Maine and back this summer, even through the mountains in WV, but I haven't attempted anything like I'd hit going West via I-70.
I know there are two basic ways to get to Estes from Denver - through Boulder or through Longmont. Does either direction have notably less elevation changes over the other? Same question about Grand Lake. Any way to get there with minimal elevation change?
Time is a factor - I don't want to add 4 hours to a 2 hour trip, but making it 3 hours instead of 2 would be OK.
Thanks
