I did think about the shelter. I have a couple lightweight pack tents which I will probably throw one in the truck. My thought process behind this was more of a ditch the vehicle and find the closest safety with a wife, toddler, and infant. Being we mainly (99%) travel the front range and west I70, I personally feel there is enough possible shelter to be found. Now, the what if factor always come into play. If there is nothing, I would stay in the vehicle for shelter! Same thing with bug out or bug in. In the next few yrs we would need to bug in, so also working on a home supply as well! Not to be to long winded!!!!
