Trailer weight vs. towing capacity

For military move purposes (we were told we could include "cargo" weight carried in our 5th wheel bunkhouse) we took out EVERYTHING from every cabinet, emptied every tank, emptied every under-belly storage, took extra bedding off of beds, etc. (Family of 5 - two adults and 3 kids)

Weighed the camper loaded and unloaded.

All the stuff we took out weighed OVER 3,000lbs. VERY eye opening experience regarding what the stuff weighs that we consider "nothing" and statements that we could "never" reach the gross weight of our campers...
