'Invalid Address/No Shipping Methods Found' when using USPS Real Time Shipping

When the order weight has exceeded 70 pounds, I get an error: "You have selected an invalid address. No Shipping Methods Found." The AppConfig: RTShipping.USPS.MaxWeight is set to 150 and orders below 70 pounds are returning rates properly.

The USPS limit is 70 pounds, unlike most other shippers whose parcel weight limit is 150 pounds.

Set the AppConfig: RTShipping.USPS.MaxWeight value to 70.
