William: My Legacy (that I did not build) and I have a lot of experience spent in the tailcone.   My airplane was built according to the manual in all respects and I can say the batteries and relays behind the seat are easy to access and out of the way of baggage.  I like them in that location.  The O2 tank, when needed, sits upright in the corner just behind the seat, secured by velcro straps and is easily accessed and pulled when needed.   I would not install anything in the tailcone that requires regular servicing just because it is a pain to access without a tail stand.  My windows do come out so it is easier but I would avoid anything non-permanent in the tailcone except my carbon luggage tube which I install from time-to-time for golf clubs.

I think O2 tanks, properly secured, are probably low risk items and moving them to the aft only makes servicing more difficult.   The riskiest times of an O2 tank are during operations with someone who might be using oil or makeup that can react with oxygen and cause burns.   Or, during filling operations with someone not trained with high pressure gasses.   Things like batteries, fuel lines, electrical circuitry and so forth IMO are more likely to be a concern and so they should be easily accessible.

Good luck with the completion too.
