Reason GVWR is used vs dry weight
IF tow vehicle is adequate to handle trailer GVWR then no issues
If tow vehicle can only handle dry weight plus X amount of cargo then an overloaded condition can easily happen.
Folks 'guesstimate' how much their stuff weighs and are usually under estimating what it really weighs.
How much does that stack of towels weigh, how about all those shoes, what about that patio mat and the chairs, toolbox, just how many shirts and what do they weigh etc etc.
Use the trailers GVWR......match truck to that and load up
Then GO to SCALES and get actual weights. If under......woohoo
If over...downsize before next trip
Yes you can tow 'trailer A' but not if you load it up........and if there is an empty space nature of folks is to FILL it.
Seen weekend campers show up and start pulling stuff out....it was like the old circus car. Stuff just kept coming out and coming out
