My suggestions are, minimize the setup for overnight stops, when I am travelling longer distances my overnight setup routine is to pull into the RV site, use the jacks to level the coach, plug in the electricity and collapse. Set up / take down time should be under 5 minutes each. There is no point in pulling out BBQ grill, camp chairs, etc. for a 12 hour stop, though occasionally it is nice to pull out the grill and do burgers, etc. Food is either something that had been cooking all day in the crock pot (which rides in the kitchen sink), or is something quick and easy to fix, frozen pizza in the microwave/convection oven, chicken strips done in the air fryer, etc. I also try to take short rest breaks every 100-125 miles give or take, my coach has about a 500 mile range on a full tank of gas, I try to stop and refuel when I hit about the half tank mark, for every 200-250 miles. If I see a scenic rest area, etc I will pull off, stretch, fix lunch, etc. again easy to fix items are key here, either something that can cook while I walk around and stretch, or sandwiches, etc. As to miles per day I try to limit it to 300-350 per day, much more than that I don't find sustainable day after day, though I have been known to push that to 500 in order to clear a large city on a Sunday evening, vs on a Monday morning, etc.
p.s. these rest breaks mid day while travelling can be practical also, for example on day 2 or 3 of a longer trip, may see a mid day grocery store stop to lay in supplies. This lets me get off the road for a bit, lets me stretch, and then be semi-refreshed for another few hours on the road, this stop may also double as a lunch stop as many grocery stores these days have a hot meal deli section.
