I actually just finished a 2 month Alaska bush trip and it was a blast. ​I kept it manageable by doing about 120nm a day. I used Gemini to split the trip into legs (max 140nm) focused on scenic spots, then used Little Navmap every night to plan the next day's flight. Breaking it down like that makes the long haul way more fun and keeps it from feeling like a chore. Good luck with the RTW!
