I think from reading your journal you are into backpacking WRC, have you built up a good kit and focused at all on lightweight and minimal gear? Basically you are taking that gear and just strapping it to a bike. Personally dont overthink it and dont over do it by taking to much, in my opinion simple is better.
I am a huge fan of just setting out from your front door on adventures, definitely go this route. I recently did this huge route from my house and it was awesome. https://www.chrisistace.com/bikepacking ... oast-loop/
I have 2 bikes I use for bikepacking, my downhill mountain bike with a simple setup of using a few bags and then just dry bags strapped to the bike. I also have a gravel bike all set up. As mentioned above every single bike will get you there and you will love traveling by bike.

My personal top pics for youtube channels for cycling and bike packing are

Great advice from Gilberto on tweaking your new bike as a good place to start. I suggest removing the front rack and panniers for wind resistance if you plan to use the trailer.
Love the trip that MoreTrees did and hope to ride from the Olympic Peninsula to SanFran when the world returns to normal.
Wow...looks like I need to make time for a 60day trip BMF1102, that Western Highland route is awesome. I did a road trip to all those spots and to see them remotely via bike would be awesome. Again as said above, come on border and Covid get back to normal.
