One of the posts claims that you really can cover lots more miles per day (160?) going faster. I don't buy it. It's not your fastest speed that depends on how far you can go but your average speed for the day and the difference in the average between 70 or more and 58 or 60 is only going to be a few miles/hr. maybe 25 or so miles more in a day, not 160. Stops and slow downs for hills and traffic will bring the averages closer together. Unless, you drive non-stop for the entire day and don't slow down for anything and that's no fun and dangerous. We've all had RV's pass us only to see them again at a rest stop down the road.

Since I'm the one that put up some figures I believe your talking about my post so lets do a little math since you don't "buy it."

8 hours of travel at 55mph is 440 miles. True?

8 hours of travel at 75mph is 600 miles. True?

600 miles - 440 miles = 160 MORE miles a day. True?

160/ day on a 2 week vacation is 2,240 MORE miles they can cover and see things. That is LOTS of more miles.

Can you show me where my math is incorrect? :h

As far as slowing down; I have a Duramax diesel and tow a 7,000 pound TT. I can set the cruise from 40 to 75 and it will hold that speed if I want it to on any hill I have been up in the US.

As far as seeing them at a rest stop down the road; that may be true. They can rest or have lunch or tour a museum or whatever for over an hour and a half and cover the same amount of distance that you can and you can't take a break; you have to drive all day without a break or seeing anything.

It goes like this: The less time you're on the road the more time it give you to __________________________ fill in the blank. :)

And your way is an advantage? :h

Ha ha, love math! But really some people are just not in a hurry and I'm okay with that. For us when we travel we are trying to get to point B as 'fast as reasonable' so we can do our riding and camping thing.I'd rather have one long day on the road at 75 then two short days on the road going 55 as it would mean more riding and camping where ever we might be going to for vacation.
