Some time in the next week I'll be towing my 42' new 5th wheel toy hauler to warm weather.  On the map it looks shorter to leave I-25 at exit 325 and take hwy 3 to I-40.  And by passing all the hills on I-25.  Would there be a advantage to taking #3?  Pulling 17,000 pounds thru the twisties is not fun like it is on my C-14.  Is there any snow still on the ground?  Thanks  Rick
