I don't know how to tell if this is the right geometry table, but........
73 deg head 45mm fork offset is a racing steering set-up.
I would like to see 450mm chainstays for panniers, to get the weight in front of the wheel spindle.
Oddly, it seems to have rack bosses....http://www.marinbikes.com/us/bikes/description/2014-lombard
There is a world of difference between wilderness touring with a tent and survival gear, and a weekend B&B touring with a credit card and clean underwear.
I can't find a "touring" fit listed on Marin's site, "endurance" fit is the closest I found.....http://www.marinbikes.com/us/bikes/road-bikes/endurance-fit
, which seems more relaxed than "pro fit" which includes Lombard.
"Endurance" geometry seems to feature 72 deg 45mm steering, a fair bit calmer than 73 deg/45mm, but paradoxically the chainstays are shorter?
To me, the "Lombard" isn't an obvious choice for a first touring bike, but then I don't know what the OP is riding now, and what his experience is.......I expect there are people who have ridden race bikes for half a lifetime who would disagree with me.
Lower gears would be useful in hilly terrain.
