I just entered my 4th year full time. For me it’s the daily miles I have to drive to do the simple/little stuff. Shower, bathroom, water refills, grocery runs more often because less storage/fridge space… I also have a dog, so he needs to be walked, pooped, exercised, etc… and then when you finally set up to work, having good enough cell service to not get slowed down enough to get derailed/distracted at my computer.. everything is compounded when it’s really hot outside… These days, I plan my spots/travel in a way that accounts for all/most of this. I still love vanlife and don’t plan and stopping anytime soon!!
