So... after doing several diff fluid changes now, and getting REAAAALY tired of figuring out how to empty the whole jug I went on a mission...
There had to be something out there to make this a simple task...
And then the answer came while wandering the aisles of Salvo daydreaming...
Fluid transfer pump...
http://store.summitracing.com/partdetail.asp?part=wmr-w1145This is a link to summit for the same thing... but Salvo had it on the shelf, as did Harbor Freight...
It was a dream come true... emptied an entire quart of fluid in about 5 pumps... refilled Bobbi's front diff with almost 2 quarts in about 5 minutes... including putting the plug back in...
Now no need to be a contortionist to figure out what angle you need to put the bottle/funnel etc. and small enough to take with me on the trails
Just 1 hose in the jug, and 1 in the diff... then pump away...
Hope it helps...
