I weighed mine with the TV once I picked it up. I wanted to know what everything was as is. I weighed my TV separately as well, with me and the DW installed.
When I loaded up the trailer for the first time, I weighed each item I put in the front storage compartment separately. Just because I wanted to know. I brought the bathroom scale out. Weighed myself, then held each item, and wrote down the weight to get to a total. That was just for the front storage compartment.
Then, once everything was loaded, as we intended to camp, I weighed it again as a complete entity.. TV, Trailer, DW and myself.
Probably didn't need the dry weight with TV, but I just wanted to know... And I wanted to understand the tongue weight percentage.
