When you go shopping for trailers, the sales people will only talk about dry weights. They have no clue about what you will be carrying in the trailer, and in many cases, those dry weights don't include propane or batteries. You'll need to take those dry weights and estimate what your loaded weight will be.
On average, a load of dishes, pots and pans, cooking utensils, BBQ gear, camp chairs. bedding, groceries, water, etc, will weigh 800 - 1000 lbs. The weight adds up very fast.
Now for the truck, it has ratings for what it can tow and for what it can carry. The tow rating was determined without passengers or cargo. Thus, as you add weight to the vehicle, it's available payload and it's tow capacity are reduced, pound for pound.
There is also a weight rating on your hitch receiver. Should be stamped with a numbers for with or without weight distribution.
There is a tire / loading sticker on your drivers door post. It will have a number for "max occupant / cargo" weight. That is your truck's capacity to carry the combined weight of people, pets, cargo, weight distributing hitch (80 - 100 lbs), and trailer tongue weight.
Here is a link to a calculator, that will give you an idea of what your max "loaded" trailer weight could be.
