Forum:Backpack SDU...57 spaces

I am currently at the Trash Coast on my 2nd playthrough. I am maxed out at level 50 and so far have 57 spaces in my backpack. The first 4 Claptraps i rescued on the 2nd playthrough gave me SDU's. How rare is this? I see some people on forums saying they think the max is 42. Have other players gotten this many? If this is really that rare i could take a picture of my tv and post it.

Not sure how to sign this....DÆ Mega
