I haven't read through all the replies, so there may be some duplication here...
Four things popped out at me:
1) Sell the Rubicon. $14K for a vehicle (much less a 12 year old Jeep??) is too much. You can find a swell 10 year old AWD for $5K.
2) Move now. You can get out of a lease, possibly with no penalty. If you landlord can find someone to take over when you leave, you should be fine (I am not a layer nor do I know CA landlord rules, but it's pretty common). It's worth trying even giving up a month's rent. One because the rent will be cheaper. Two, your commute is going to get 10x worse when the snows hit. If you work in the park, you should live in the park. You will save on gas, and you won't evenn need a second mountain car.
3) Shop for insurance. Insurance is $138? That seems high. We have two vehicles and pay $500 / year through Geico. Maybe you have comprehensive on both vehicles? Get rid of it on the Commander. Sell the Rubicon and get just liability on both. Shop around.
4) You have a landline plus internet? You can probably save $100 - $250 a year by dropping the landline. Skype and other free VOIP make a landline redundant.
5) Storage. Close it down effective December 1st.
However, those may just be bandaids. If you really want to be happy, seriously consider the possibility that you could quit your job, move to a LCOL area, raise your kids yourself, and live off your wife's salary. You may find this leads to a more rewarding life, financially and emotionally.
Good luck!
