For years I used Streets and Trips and it worked well. I have recently discovered
www.rvtripwizard.com. I think it is a vast improvement over anything else I've ever used. In fact, it is almost amazing. The website has a demo and user guide. I pay $37 a year but can cancel. We take a 3 month trip each year so it is very helpful and worth the money for me.
The program allows you to enter which RV parks you want to see - for instance, I select Passport America, city and county parks, Corp of Engineers and many more. The POI (points of interest) has Walmarts, Casinos, and many more. It is terrific to have all these in one location.
Another feature is that it allows you to enter how many miles you want to travel in a day, up to 3. I enter 200, 240, and 280. A circle is formed that allows me to see parks located around each destination.
I've used it on my laptop and it works well. I use it on my iPad, but they are currently having some program issues since Apple just published a new system.
It's a small company and I got an immediate email from the president when I found the iPad problem.
I love this program, but I always have paper maps with me. I guess that stems from my years of travel with my parents. I would be interested in what you all think about trip wizard if you try out the demo.
