how far to drive every day

Only you can determine that. What is your tolerance for sitting behind the wheel? Where do you want to stop and what do you want to see? On a trip like you are planning you have to be flexible with you itinerary so that might mean you find you want to stay in a certain area for more days than you initially planned on.... or less days, either way.

On our big circle trip we covered 8635 miles and took 10 weeks. Northern route out to the Olympic Penn. and southern route back home. Sometimes I drove 10 hrs a day other days it may have been 5 or 6 depending on the next destination stop. Don't over think things but have a good idea of what you want to see and do and go with the flow. We only made reservations for our destinations where we stayed more than 2 to 4 days. Any overnight stops were on the fly and we never had a place say they were full up. We used the RVParky app to find those overnight stops.

Go on-line and order the travel planners for each state you plan on going to. They are a wealth of information and give a good insight to what you may be interested in seeing....even things you didn't know about. Its a big beautiful country so take the time to see it up close. Can't beat the RVing experience doing that.

Available time and total distance and points of interest along the way mixed with your own stamina, and the roads you select all factor into the equation, and only you have the exact math formula that works for you.

Of course, the longer time you have, the less rushed you have to be. You can spend a single night every night and might only move 50 miles, or you might want to move 500 miles and push to do that in a single driving session. It's really your call.

Now, if you ask ME what my ideal is ... well ... for me, it's 6 hours of actual driving time a day. Now if the speed limit is 45 mph for 6 hours, the distance of course is shorter than 6 hours at 70 mph the distance is longer. There again, the road or the route we take will determine how far we travel to. But we shoot for 6 hours of actual, behind the wheel time. Why?

Because we don't like to arrive at a campsite so late it's dark and because we've never been there before, have difficulty backing into a campsite in unfamiliar territory.

Because we don't like to arrive so late, we can't spend some time exploring the campground.

Because we don't want to push the driving so hard we are just worn out.

Because we want to set up camp enough, we can fix a good supper. After driving, eating sandwiches or fast food all day, it's nice to finally take the time and eat real food.

Sometimes, it's nice to build a camp fire and vegetate. Arriving earlier in the day give us the luxury of that time to do so.

Six hours of driving a day also means you don't have to push so hard in the morning, getting out of bed, rushing around, breaking camp just so you can get on the road. It means you can take the time for a decent breakfast, get a good shower, and take the time in the morning to check your rig, engine oil, tires, hitching, everything, so you know when you hit the road everything is functional and in good operation.

The other reason for a limit of 6 hours driving, if we see something along the way, we don't mind stopping and spending an hour or two. We see something interesting advertised on the side of the road, we go ahead an pull in, stop, and pay a visit. We've seen and eaten at some really great places that would have been missed otherwise.

Another reason for a 6 hour limit? Well, if the inevitable happens (mechanical failure), the time involved it takes to fix the problem will not stress you out, thinking you absolutely MUST drive "X" number of miles today or I'll miss my goal! Anticipating break-down time is a must.

Another reason is ... well ... simply ... we are on vacation. Why in the world should we rush so much! It doesn't matter if we are at 5 star luxury RV resort, or in a parking lot, we are on vacation, we are traveling to see this magnificent country and to experience all it's local color. Why rush through?

Six hours is just right for us.

We like to travel about 350 miles per day. That gets us set up at campground during day light ... We are retired so not in any hurry at all. Jim 20th

Cold beer, Bob?

I like to drive no more than 6 hours per day. This keeps you from getting too tired and helps with the enjoyment of the trip more. I like to get-up leisurely in the morning, have coffee and breakfast and walk the dogs, then break camp by 10 am. I like to stop at about 4:00 pm, make camp, walk the dogs, have a beer, eat a nice supper and then enjoy sitting outside for a while. Remember, when traveling in a RV, it's more about the journey than the destination.

It really depends on how close together the stops you really want to make will be. Layout the distances between your "must do" stops, then look at those distances and see if there is anything that might interest you in between them. If so, drive less and at the additional stop; if not, then take a day to make a longer drive.

It's really a personal choice that starts with your comfort level regarding driving and ends with your desires for the trip.

It sounds like you are on a wonderful adventure.
Pick a couple of personal "Gotta do it" places.
You said Vegas, I will suggest that you do that early in your trip, because you may decide that stops like that are not really all that important.
Many find that the magnificance of the natural world dwarf's what man can stack on its end.
Enjoy your trip.

I follow the 230 / 2:30 rule stopping when I've covered 230 miles or it's 2:30 pm. It's up to you!

Whatever it takes for that time frame to see all you want to see. There may be days you do 500 miles. Days you do 50 miles. And days you don't move. Max miles (or max hours) on any given day is what you are comfortable with.
