Walter,

   The flying LIV's I've been around have tended to the tail-heavy side, and  this will eat into your ability to realize your full useful load capability without running into rearward CG problems.  So I'd think carefully about
adding more stuff to the rear than you have to.  BUT, whether you're heavy in   the nose or in the tail, you might want to take a more calculated approach to your remaining decisions re. placement of stuff.
    I like the way my cg turned out, and I got there by borrowing the actual w&b  sheet from a flying IV similar to mine, listing the arm and weight of each  piece of their equip, and using that to calculate a projected w&b for my  plane. Each critical decision for  selection and location of my stuff  was then played against this projection with a goal of ending up exactly at the  forward cg limit when down to minimum flying weight (e.w. plus pilot plus  min. landing fuel).  This calculated approach worked out pretty well...when I weighed the completed plane my minimum flying weight cg came out just 0.5  inch aft of the forward limit.
Good luck,   Ken Lanham.
