This is really a good idea. Our last RV was a 30 ft bumper pull with a couple of slides. Our truck is a 4 door long bed dully. We pretty much had to be careful that we didn't pull into a park that couldn't accommodate our rig. Also a concern was getting into a place that would be hard to get out of. With the RW that is even more a concern.
I have all of the apps mentioned here. But with the size of the RW, we're pretty much all in the same boat and would have the same size needs. It would be great not to have to sift through all the info in the apps that are available. Also as said here, their big rig friendly might not fit our big rig.
