I agree Manuvering with any sort of pack is a skill you don't want to learn on the fly. Your bugout plans seems somewhat linear which is very thought out. Our locations are not. We will have to discuss that among our group because our tertiary location isn't going to be something we could get to on foot from the secondary location. We may have to discuss a plan 3A lol in case foot travel is our only mode. The good thing about your tertiary location is that prepositioning a lot of gear may not be absolutely necessary because you can grab and go from the second location as you go hopefully.
I agree to all of that. Always makes me laugh to see people wanting to carry 400+ rnds three weapons and a 80lb ruck.
