That's roughly when they forsee being ready to get their kids' stuff. I'd seriously doubt, given their economic situation, any earlier, but it certainly could be delayed until the Spring. I just thought a southerly route would help. Maybe I-20 would be better than 40 once we're beyond Texas...
I also might add that in planning road trips, I come up with several contingency plans - hence my post: looking for good suggestions!
Another very important thing to consider - your U-Haul is a very attractive treat for thieves while parked at a motel.
I’m not sure what’s the best way to protect the kids’ stuff, other than parking in front under plenty of light and perhaps rigging an alarm...
