Awesome! I do lots of the minimalistic stuff when I do motorcycle camping.
I think these pack lists for your bike do a great job prepping you for the step to vehicles. I remember putting a wrench on every bolt, leaving behind anything the DR650 or KLR650 wouldn't use to save weight.
It was a natural progression from ultra light backpacking to car camping for us, but we never get it perfect and that is part of the fun.
Several "steps" in the transition for us:
We made several big steps as we went from backpacking to car camping to what I will now call expedition camping:
We went from homemade dried foods, to sandwiches and soups, to more complex meals.
We went from no cooler, to an ice cooler to now an ARB.
We went from a tight two person tent, to a three person tent for two, to a 6 person tent (even for just two of us now

)
We went from a 1.5" to a 2.5" to now an 8" air mattress.
We went from a sleeping bags to now sheets and a bag only if needed, but most of the time the bag is used as a comforter.
We have added fans and dual batteries and back up batteries.
We have added fold up chairs and light weight tables, when it used to be just cook off the ground
We enjoy campgrounds at times for electricity and water - - especially if away from it for a few days and need to resupply, charge, etc.
All of this can be done without sacrificing EVERYTHING in the outdoors, I believe.
Hard to tell but right behind us is a pizza place with great beer . . . never had that before "camping"
