Crucial Factors:
* Trailer's Gross Vehicle Weight Rating (GVWR): This is the maximum weight the trailer can be, including its contents. This is the most important number.
* Trailer's Tongue Weight: This is the weight pressing down on the hitch of your Blazer. Too much tongue weight can make the Blazer unstable and difficult to control. It's typically around 10-15% of the GVWR.
* Blazer's Towing Capacity: The 2004 Blazer's towing capacity varies depending on the trim level and options. You must consult your owner's manual to find the *official* towing capacity for your specific vehicle. This number will likely be significantly less than what many people assume.
* Terrain: Towing uphill will significantly reduce your effective towing capacity.
* Cargo in the Blazer: The more weight you have in the Blazer, the less it can tow safely.
In short: Don't just look at the length. Find the GVWR and tongue weight of the trailer and compare them to your Blazer's towing capacity (found in your owner's manual). If the trailer's GVWR and tongue weight are within the Blazer's rated capacity, it *might* be possible, but it will likely be a struggle and not ideal for safe towing, especially in hilly or mountainous terrain. A larger SUV or truck would be a much safer and more comfortable option for towing a 24-foot travel trailer. Underpowering your towing vehicle is dangerous.
