My brother and I are travelling to Durango, CO in mid October for the 1st week of a 2 week trip. We plan to travel around the CO, UT, NM area, while staying in Durango. The 2nd week will be Las Vegas, NV.

Accuweather.com is currently calling for temperatures in Durango to be highs of around 60 and lows around 28, and then in Las Vegas to have highs in the mid 70's and lows in the mid 50's.

Due to all of this I am wondering how to best pack for this, while not having to take more than one suitcase and one carry-on a piece. We do expect to have to do wash at least once, probably before we leave Durango. We are mainly concerned with pants. Tend to wear short sleeves year round, and will take at least a light jacket.

Any suggestions? Right now we are probably going with jeans for Durango and shorts for LV, which means more pants than we normally have to pack. Tried purchasing a pair of convertible pants, but they did not seem that comfortable and the cargo type side pockets were higher on the leg than I would have liked. My brother and I are on the larger side, btw.

Thanks for any advise you can give us.
