Re: ERV Tankage

Would a MarsDirect ERV need two sets of LOX and H2/CH4 tanks, or would one set that gets refuelled onsite be sufficient?

*After landing and fuelling the ascent tanks, the descent tanks could also be filled for general base use (powering rovers, backup generators, etc)
*The ascent engines could be separate to the descent engines, eliminating the need for a restartable engine (but with the obvious disadvantage of additional weight)
