I wish I could carry a G17 but am restricted to my G26. The G17 is just perfect for mountain carry since the longer barrel gives quality 9mm rounds just a little more uhmf than the G26 barrel. Another reason I love my G17L especially if I'm not going to worry too much about concealment.
Of course all Glocks are great in 'weather' either up in the mountains or down in the desert.
G17 is a good choice for a road trip. Always carry enough gun for the trip. At minimum I go with the G26.
