Travel Trailers will weigh different amounts depending on the construction materials used in making of the traveler trailer.
Some 24 foot travel trailers will weigh less than another 24 foot travel trailer.
On average though the average 24 foot travel trailer weighs around 3,715 pounds without gear and water in the tanks.
When you add the camping gear and water in the tanks then the weight of the 24 foot travel trailer could go up to 4,000 lbs which is 2 tons.
A 1/2 ton to 3/4 ton pickup can usually easily pull the 24 foot travel trailer without a problem as long as your truck has electric brakes.
I'd also recommend adding a transmission cooler to the transmission if your transmission doesn't have one especially when climbing hills on your travel trailer trip.
