I use Trip Wizard as well and have used many others... interesting factoid:RV Trip Wizard was acquired by this (MOC) forums owner a few years ago and has been in steady update mode ever since. it's come a long way in a short while.
The database of parks is enormous and driven by the data from campgroundreviews.com. There is a brand new (a day ago) update to use RV safe routing to avoid parkways and propane restricted tunnels as well as unpaved roads (if you want).
Also new with todays release is that it can sync with the RVLife app. The RVLife app is free (although it has some premium-paid options to download maps and park info for offline use) and is essentially the mobile version of Campgroundreviews.com. Now, if you have the app installed, you can access your Trip Wizard trips while on the road more easily. Trip wizard has a steep learning curve - it does a lot but it also takes some time to get comfortable configuring trips; it's not for everyone.
^ all of that reads like a commercial but it's pretty good and getting better every day. It's not perfect yet, but it's nice to know that real RVers are developing the platform.
here's a link to the newest features tour:
