Keith,
Add a small header tank near the firewall. It allows you to carry the extra weight when the plane is full of fuel, but it comes back out when you drain the plane for weighing. An empty header tank will weigh much less than the weight you are carrying, and accomplish the same thing without hurting before weighing.
