when we finally purchased our class c I had already done quite a bit of reading and found a site that offered a print out "check-list."
I printed that and for the first several trips added some things while removing others that did not pertain to our situation.
I now have what I feel is a decent list including "clothes." second outing we forgot our clothes!
I now have a three ring binder that I have several copies of the list and have added a top section with where we stayed, dates, mileage, thoughts on GC etc.
we both do a walk around before we leave the house and then when we leave the GC
I get the book out and go over our list.
nice to have the details and a few thoughts on each of our trips.
