I travel frequently for work, but have never left my son for more than 3 nights. I don't think I could do 14 days- that's a LONG time for the baby.
I'm only sharing this with you b/c it's my experience, but after my last business trip, my son was overly excited that I was home. While I was thrilled that he missed me, he was literally attached to me and started waking up at night to make sure I was home. He's older (almost 3), so I asked him what was wrong and he responded very simply "I thought I lost you".
Two weeks is too long for either of you to be away from the baby. I would suggest finding a way to "split it". Could the baby come with you for a week and then go home for a week? You say it's "very far", but if both you and hubby drove and met "half way" it may not be so bad.
Your husband will be fine with your baby- he will do things differently, but that's okay. The toilet seat will be left up and the baby will stick his hands in, but hopefully dad will wash his hand quickly. He may not bathe him every day, but he will be loved-fed-bathed-and diapered.
JMO... find a way to split the time so that neither of you is away for this long. Children are VERY sensitive to having their parents away, even for short periods of time, b/c they are simply unable to understand "time" and at that age 3 or 4 days feels like "forever".
