No OCD stuff on my list. In only 9 years of motorhome RV'ing I've had to make use of most everything on the list except some of the tire repair items I just added this past summer before our 10,000+ mile RV trip this fall. I keep the rig almost fully loaded per my list at all times between trips ... so there is no extensive packing required for the next trip. BTW, my full list is longer than the one I posted above.
My experiential based RV philosophy is this: You can't bring too much along ... only more than you can fit or more than your rig's weight rating allows.
I can of course "fit" all that I bring along - BTW with no trailers, outside racks, carriers, or ladder straps required. Everything is carried enclosed in drawers or inside/outside cabinets . As far as weight is concerned, I anticipated this up front by originally buying a small motorhome that could have been carried by the Ford E350 chassis but instead was built on the optional Ford E450 chassis. We have about 2000 lbs. of extra CCC capacity with the E450 over and above what a fully loaded RV our size would weigh as owned and/or operated by "non-OCD" RV'ers. What I am "OCD" about is having an otherwise spectacular RV trip ruined, seriously compromized, or threatened by safety issues that didn't need to be.
What you can't bring along is another RV: Our traveling couple companions this fall, early in the trip with us, totaled their RV thousands of miles from home and had to terminate their trip and return home.
P.S. We have at times brought home quite a load of rocks, too. ;)
