What trip planned do you use

The state atlases you refer to are probably DeLorme atlases. They are quite complete...perhaps more complete than one needs for most RVs. Interestingly, the DeLorme company was bought out by Garmin.

I like Good Sam very much. I also incorporate tripadvisor especially when we get to small towns and the town just looks cool. It will tell you of the local attractions and things to do + good places to eat.

We use folding paper maps, a Rand McNally atlas and google/maps when it is available. We like to run on the State and local highways and roads. We get to see so much more that way. We figure 200 to 225 miles per day. That night we Google for RV campgrounds near that ending point for the next day, checkout which campgrounds have what we want, give them a call to reserve our spot. Next day we leave around 9am and take our time arriving at the reserved campground site around 3pm. We went to Mesa Verde and back last year using this method and never had a problem. Of course our Class C is a 22 ft so we could fit in just about anywhere. We are going to Washington state from Seekonk Ma. this summer using this method. What I did differently this year is print out the available campsites along the way (route 2 west from Sault St Marie)so if the camp we are at doesn't have Wi-Fi and we have no service on our cell we just look up where we want to stay the next day.

Thanks everyone for your replies. DDDUUUUHHHH, I had forgotten about using a atlas or state maps. Wonder where that went. Lost somewhere. You usually can't go wrong with either of those.
Kinda got this mental block that I had to use the computer. At my age, not sure why? I guess I like tech stuff.
Once when the DW and I were visiting the son and family at their home NW of Chicago. They live close to the WI border. We wanted to visit some friends up in Door county. I said I needed to get a WI state map, son says, he had one. He gets me a 1/2 thick 12x14 or so spiral bound map of WI. It has been the best map I have ever seen. It had every road in it. Inclucing the dirt road our friends lived down. I checked the state map and it did not have the dirt road. Can't remember the nave of the company that produce the map. The last time I checked they were still producing them. Trouble is, you have to buy a book for every state. Now that would be a stack of maps.
Well somehow I was able to lose this post, so I typed the other post and now here it is. Not to good on this computer. LOL, but I have a ton of fun.

Thanks everyone for the replies. DDDUUUHHHH, I don't know why, but I had kinda drifted away from the atlas and state maps. And you won't go wrong using a state map. I will be going through my pile of state maps.
2gypsies, I too, like to hit the back roads. That is where you see real America.

I've always started with a good road atlas or individual state map. It's a lot easier to see what's out there and the road directions than using a computer-based trip planner. When we get the route defined then I put it in the GPS.

You'd never see anything if you just put in from A to B and take off. We like to meander the secondary roads.

I figure out how far I want to go in a given day, find a nearby town and search for amenities nearby. Do this for each leg of the trip in advance. It's always worked well for me.

I use the Rand McNally Large Scale road atlas, AAA tourbooks, Google maps, etc. For me, the lower-tech (or at least lower-integration) approach seems to work out pretty well. Often the planning is only in rather broad strokes (i.e. destinations and a rough idea of a possible route), with more specific routing and such being figured out on the day of travel.

For weekend trips, often the planning is dictated by what state parks in the area have sites available that look reasonable for my RV...and have hiking trails or whatever available that look reasonable to me.

I have used the Good Sam planner. It worked well for me when I took a trip,from FL to NY and back. I plan all my trips before I leave home.
