Types of Trailers: 15 Trailer Types Explained with Weight and Size Guide

Key Takeaways

• 15 trailer types cover everything from yard work to cross-country freight
• Utility trailers are the most versatile entry point at $500-$1,500 new
• Bumper-pull trailers work up to ~14,000 lbs GVWR; heavier loads need gooseneck or fifth-wheel
• Enclosed trailers weigh 30-50% more than equivalent open trailers
• Always match the trailer to your tow vehicle's GCWR, not just towing capacity

Choosing the wrong trailer type wastes money and creates safety problems. An open utility trailer can't protect expensive equipment from rain. A bumper-pull car hauler at 10,000 lbs loaded pushes most half-ton trucks past their limits. And a full-size enclosed trailer behind a midsize SUV is a recipe for a trailer sway incident. This guide breaks down every common trailer type with real weights, typical costs, and the tow vehicles that match each one.

Consumer trailers fall into six main categories: utility, enclosed cargo, travel/camping, boat, car hauler, and specialty. Each is designed around a specific use case.

Utility trailers are the Swiss army knife of trailers. A single-axle 5x8 handles landscaping supplies, furniture, appliances, ATVs, and general hauling. Add mesh sides for yard waste, a ramp gate for equipment, or stake sides for lumber. Most half-ton trucks and even some SUVs can tow the smaller models.

Enclosed cargo trailers add walls, a roof, and a locking door to the utility trailer concept. They protect tools, equipment, and materials from weather and theft. The trade-off is weight — an enclosed 6x12 weighs 1,800-2,500 lbs empty versus 800-1,200 lbs for an open utility trailer of the same size.

Travel trailers are the most popular RV type, outselling motorhomes and fifth-wheels combined. They range from minimalist 16-foot models towable by an SUV to 35-foot triple-slide units that need a heavy-duty truck. Read our travel trailer towing guide for detailed matching advice.

Pro Tip: Aluminum utility trailers cost 20-40% more than steel but weigh 30-50% less. If you have a lighter tow vehicle, the weight savings can mean the difference between being within capacity and being overloaded. Aluminum also doesn't rust, which extends the trailer's lifespan by decades.

Most consumer trailers use a bumper-pull (receiver hitch) connection, but larger and heavier trailers require a gooseneck or fifth-wheel hitch mounted in the truck bed. The dividing line is roughly 14,000 lbs GVWR.

Bumper-pull trailers (receiver hitch at the rear bumper):

• All utility trailers up to 7,000 lbs GVWR
• Enclosed cargo trailers up to 14,000 lbs GVWR
• Travel trailers up to 10,000 lbs GVWR
• Boat trailers (virtually all)
• Open car haulers up to 14,000 lbs GVWR

Gooseneck trailers (ball in the truck bed):

• Flatbed gooseneck trailers (14,000-25,000 lbs GVWR)
• Large equipment trailers
• Car haulers over 14,000 lbs
• Livestock trailers
• Large dump trailers

Fifth-wheel trailers (pin-and-plate coupling in the truck bed):

• Fifth-wheel RVs (10,000-20,000 lbs GVWR)
• Commercial semi-trailers (up to 80,000 lbs GCWR)

The advantage of gooseneck and fifth-wheel hitches is the coupling point sits directly over the rear axle instead of behind the bumper. This moves the tongue weight closer to the truck's center of gravity, improving stability, reducing sway, and allowing higher tow ratings. Most 3/4-ton and 1-ton trucks are rated for significantly more weight with a gooseneck hitch than with a receiver hitch.

Key Insight: A gooseneck hitch requires a truck bed — you can't install one on an SUV, van, or car. If you need to tow over 14,000 lbs, you need a pickup truck. This is why heavy equipment trailers, large livestock trailers, and big flatbeds are almost exclusively pulled by 3/4-ton and 1-ton pickups.

Beyond consumer trailers, the commercial world uses several specialized trailer types designed for specific cargo categories.

Flatbed trailers are open platforms with no sides or roof. Commercial flatbeds run 48-53 feet long and haul construction materials, heavy equipment, steel, lumber, and oversized loads. Smaller flatbed trailers (16-24 feet) serve landscaping companies, contractors, and equipment rental businesses.

Dump trailers have hydraulic lift systems that tilt the bed to dump loose materials — gravel, soil, mulch, demolition debris, and sand. Small dump trailers (5x8 to 7x14) with 5-7 ton capacity are popular with landscapers and contractors. They require a hydraulic pump powered by the tow vehicle's electrical system or a dedicated battery pack.

Dry van trailers (box trailers) are the enclosed 53-foot trailers you see behind semi-trucks on every highway. They're the backbone of the freight industry, carrying palletized goods, consumer products, and general freight. Consumer-scale versions exist as enclosed cargo trailers from 5x8 to 8.5x24.

Refrigerated trailers (reefers) are temperature-controlled enclosed trailers for perishable goods — food, pharmaceuticals, and chemicals. The refrigeration unit runs on diesel or electric power and maintains temperatures from -20°F to 65°F. Small reefer trailers exist for catering and food delivery businesses.

Lowboy trailers ride extremely close to the ground with a deck height of 18-24 inches versus 48-60 inches for standard flatbeds. They're built for hauling tall and heavy equipment — excavators, bulldozers, cranes, and industrial machinery that exceed standard height limits on a regular flatbed.

Tank trailers haul liquids — fuel, water, chemicals, and food-grade liquids like milk and juice. They come in pressurized and non-pressurized configurations with various materials (stainless steel, aluminum, carbon steel) depending on the cargo.

Common Mistake: Assuming a CDL (Commercial Driver's License) is only needed for semi-trucks. Any trailer combination over 26,001 lbs GCWR requires a CDL, regardless of the tow vehicle. A 1-ton dually pulling a large gooseneck equipment trailer can exceed this threshold easily.

Picking the right trailer starts with three questions: what are you hauling, how much does it weigh, and what can your tow vehicle handle?

Step 1: Define the load. What are you carrying? Furniture and general items need an open utility or enclosed trailer. A vehicle needs a car hauler. A boat needs a boat trailer. Camping gear needs a travel trailer or tent — don't overcomplicate it.

Step 2: Estimate total weight. Add the weight of your cargo to the empty weight of the trailer type you're considering. A 6x12 enclosed trailer at 2,000 lbs empty plus 3,000 lbs of tools and equipment equals 5,000 lbs. That's your loaded trailer weight.

Step 3: Check your tow vehicle. Your loaded trailer weight must be under your vehicle's towing capacity. But also check payload capacity — the tongue weight (10-15% of trailer weight) counts against your payload. And check GCWR — the combined weight of the tow vehicle, passengers, cargo, trailer, and trailer cargo must not exceed it.

Step 4: Consider frequency. If you tow twice a year, renting a trailer for $50-$100 per day often makes more sense than buying. If you tow monthly or more, buying saves money within the first year. High-use trailers like work utility trailers and daily-use equipment trailers should be bought, not rented.

Step 5: Match the hitch. Ensure your tow vehicle has the correct hitch type for the trailer you're considering. Most receiver hitches come in Class I through Class V ratings — the trailer's coupler size and weight must match the hitch class.

For boat towing or RV towing, we have dedicated guides that walk through the specific considerations for those trailer types.

Pro Tip: Buy one size larger than you think you need. A 5x10 utility trailer handles everything a 5x8 does, plus the jobs where you wish you had 2 extra feet. The price difference between adjacent sizes is typically $200-$400 — much less than buying a second trailer when the smaller one doesn't fit your needs.

Trailer laws vary by state, but several federal and common state regulations apply to most trailer owners.

Federal brake requirements. FMCSA requires trailers over 3,000 lbs GVWR to have their own braking system — either electric or hydraulic surge brakes. Many states set the threshold lower at 1,500-3,000 lbs. Check your state's specific requirement before purchasing an unbraked trailer.

Registration and titling. Most states require trailers to be registered and titled like vehicles. Homemade trailers typically need a VIN inspection and weight certification before registration. Some states exempt very light trailers (under 1,500 lbs GVWR) from registration.

Lighting requirements. All trailers towed on public roads must have tail lights, brake lights, turn signals, side reflectors, and a rear license plate light. Trailers over 80 inches wide also need clearance lights and side marker lights. This is why proper trailer wiring matters.

Speed limits. Many states impose lower speed limits when towing — typically 55-65 mph versus 70-75 mph for non-towing vehicles. Some states also restrict trailers from the left lane on multi-lane highways.

Weight distribution hitches are required by many trailer manufacturers for loads over 5,000 lbs and are strongly recommended for any trailer that exceeds 50% of the tow vehicle's weight.

Key Insight: Even if your state doesn't require trailer brakes at your GVWR, your trailer manufacturer or tow vehicle manufacturer may require them as a condition of the warranty. Check both your trailer's owner manual and your tow vehicle's towing guide before deciding to tow an unbraked trailer near its capacity limit.
