Do you use 5D III plus 24-105 as travel camera?

I am thinking about buying 5D Mark III as a complement to my Pentax K-5 and compact Canon G1X. The reason would be better zoom lenses and thus better IQ. Greater DR with 5D is also tempting.

I shoot travel pictures, landscape, portrait, macro, street (mostly with my G1X), architecture, and more. I always shoot in raw format. I use Adobe PS CS6.

Now, I often use my K-5 with the Pentax 18-135 lens (effectively 28-202 mm full frame). This is a good combination when traveling, small and light, and with a good zoom range.

If I buy the 5D, then I could possibly take it with me when travelling, but probably only with one lens then, the 24-105. I am not sure that the zoom range would be enough. OK, when doing travels in nature, like Greenland (I was in Antarctica last year), then I might also bring a big 70-200, but if I go to cities or to warm countries, then I want a light burden.

Do you have experience of 5D with 24-105 as travel camera? How about the zoom range?
