I have to agree with Gerald and Larry, Randy. Since both hot and cold are weak, it's likely that debris or calcium has blocked off your aerator screen. It's not likely that both your hot and cold bathroom manifold valves are inadvertantly and equally closed off, though if the aerator is not fouled, check the manifold too, as Gerald suggests.
And if as suspected your aerator isn't whistle clean, I'd remove and check any other faucet aerators in the coach while I'm at it. They're all fed from the same sources and probably all could use cleaning.
Let us know the outcome.
