I started out using the same tools for geocache trip planning, but quickly realized it was unwieldy.
Geocaching Swiss Army Knife application (Windows only) a couple years ago, and it has become a key tool for me. It has a relatively steep learning curve, but has huge benefits, including a large and growing macro library that add specific functionality as needed.
I'll often create a database of "maybe" caches in an area, view them on the map, and then pick out caches that have easy access for the RV for further consideration.
The Nuvi_GPX_v2.Gsk macro puts all the caches in the selected database on the Nuvi as Points of Interest with appropriate icons to indicate the type of cache. In this picture, there are three traditional caches, one nearly hidden under the helicopter that represents our rig.
In the upper left, the Nuvi is indicating that Route Point 3 (I haven't found a way to change "Route Point" terminology) is on the left, 11 miles further. The waypoints are created using the CacheRoute3.gsk macro.
All of that helps with trip planning and navigating to the area, but it wasn't doing anything for my desire for a printed list of caches. If I'm out for the day, I carry a small notebook to note anything special about the various caches, but that doesn't provide enough structure when I'm doing a road trip that could involve dozens to hundreds of potential caches.
Cachetur! I heard about Cachetur on a Facebook group associated with Project-GC (another very helpful online tool.) Cachetur is a free, user supported, online trip planning tool for geocaching that originates in Norway.
I used this style for my southern Arizona, New Mexico loop and appreciated everything but the number of pages it took!
So far, I haven't found a way to build a custom report style but I'm still looking. Meanwhile, Cachetur has become an important tool in the arsenal for geocache oriented road trips, and I'll keep learning about its capabilities.
