Hey Juicers! I need help!

I'm very new at juicing and probably should have waited another 2 weeks to start. Next week I'm going out of town. I'm leaving on Wednesday to drive to NJ. Packing up my mother on Friday and heading back to Iowa that very same day. This is going to have me on the road for 4, maybe 5 days depending on how long the packing takes. I'll have ZERO opportunities for juicing while I'm gone. Any ideas how to pull this off? I've read that anything I run through the juicer should be used no later than 48 best by 24. I'm taking a cooler with me since I'll have my youngest child and my brother with me so I can keep some glass jars cold but 48 hours isn't going to get me through the trip.

Ideas or suggestions???
