Great question. I still want to retain the use of "most" of my bed. So that really left me looking at GFC, VB, and ACCC (and a few others). The ACCC looks like the best bang for your buck and the modularity was a huge sell for me. I also really like the size and interior design of it. The rear swing door is a great option. From all of my research there is no true solution, only trade offs
.
All of what your said rings true.
I was considering an 80 or 100 series for the longest time with a Campteq popup on it --- till I saw the accc and started looking for a Tacoma the next day! (I have owned a truck camper - hated it)
What I like about the accc
1st on my list would be the popup on the accc - I would not even have considered it without the inside access sleeping area and being able to stand up in it.
2nd the gull-wing doors appear to be so convenient to access stuff when at camp while not having to climb in and out of it & provides a more open space/feel when hanging inside.
3rd huge back door
& 4th Apparently Alu-Cab has great build quality
Everything else is just a bonus and as you said all these sort of things are a compremise.
