If you and I lift an object together, we're each essentially lifting half the weight, more or less (I'm sorry, I was tilting it more towards you to get the lighter load... won't happen again).
But cutting the DC to 10 for two and to 7 for three seems perhaps maybe almost too easy (ymmv). Of course, if everybody has to make a roll vs that DC, it might not be as easy as it sounds...
Reduce the DC by the number of 'extra' folk, and make one d20 roll adding all of their STR modifiers?
