Sounds reasonable to me, prubin.
I usually tip, and I give the entire tip to the moving team lead while they are bringing things from the truck into the destination home. I tell him in front of the other movers that this is for all of them and to split the tip fairly between them all. Perhaps I should have gone to each individually. For three movers and one lead mover doing an excellent job I tipped $100 last time, and I do not tip lavishly.
