The new information puts a new face on things. Most of the time, less travel means more time at home. Here, the job with less travel gives you less time at home. The new job would have to offer more money, not to make up for travel perks, but to make up for that. They're asking you to give up a lot of time with your wife, and the rest of it doing something you get a personal kick out of, instead of sitting in a cubicle. Personally, I'd say it has to offer enough more that you couldn't turn it down and she'd agree - not just go along, but because she really sees professional advancement in it for you.
