This sounds like a thread about traveling after retirement? We are not there yet, but I am beginning to look forward to it.
We have limited days, so we travel with a purpose. We usually have a full fridge. I rarely carry water in the camper's fresh water tank. If we really need to use the bathroom in the camper while on the road (on some occasions the wife has refused to use the rest stop bathroom due to its' condition(!)), I've got no problem with using the black tank until we get to the campground - if needed, a bottle of water to help with flushing.
Since we rarely have extra time, we don't make detours while traveling to a destination. We do try to keep in mind places / attractions we pass by, for possible future trips. I think I will love the time when we can just stop wherever we happen to be to do whatever we want, without a schedule.
Wife and I have started to think about a "retirement" camper. Lots of options and ideas to think about!
