We drive 250 to 300 miles a day, simply because we can. There is no reason to rush and I have proved I can do a marathon drive more times than I care to admit. Now I do not have or care to do it.
I carry all the tool I need to change out a tire and I carry good road side service for real emergencies.
Most of my supplies come from Amazon or eBay but I use CW for parts I need to touch or feel.
We rarely reserve campsites unless we are traveling to certain popular spots. Spring break in AZ comes to mind.
How and what one does depends on their particular circumstance. Coming from a wilderness canoe and tent background there is not much that bothers the DW and I when RVing.
