depends on what kind of trip. If it is a camping trip I dig out my old streets and trips. Yes it's old, yes it doesn't have latest road updates. However (a) it's easy to do a route taking backroads and the route i want (b) I put in how often and long rest stops are (c) how many miles for gas (d) when we usually start (e) when we want to stop for the day (f) what our average speed is vs speed limits.
so... pretty quick it can give me a daily trip plan, which we can then tweak based on best place to stop, where to plan for gas etc.
Then depending on what our plan shows and what we know I either then just use my Garmin RV for directions, or import the streets and trips route to basecamp then to the garmin RV for a route,
For "normal" trips, not towing google maps on the phone with android auto to the car display, Nice thing about google maps is it is pretty accurate about time and picking a route around traffic holdups.
And on more than one occasion while towing when we hit a traffic stop I just hit onstar and had the operator route us around telling them I am pulling a 35ft trailer, They then did a route suitable for the trailer.
I've also used the onstar service on occasion when I wanted a very specific route. For example, San Diego to Cresent city staying on highway 1 as much as possible and using 101 as an alternate. routing through San Fran was fantastic. Down to 'in 3 blocks be in the right lane to turn on xxx street. a block before the right turn you will pass a McDonalds. turn right at xxxx street. There will be a xxx store at the corner".
if we are going to explore any FS road etc. For most locations we visit I have paper copies of 24K:1 topo maps, problem is they aren't updated very often. Along with that if it's a new area I download Avenza maps. USFS is now putting many of the MVUM on Avenza for free.
MVUM show where we an legally ride on FS land with our dual sport motorcycles. Nice to use those maps to get to old FS lookouts, etc.
And if all else fails, I pull out my garmin montana with 24K:1 maps loaded or my garmin inreach likewise.
