How to Choose a Stacker Trailer
A stacker trailer is a big purchase and a long-term one; most owners keep them for a decade or more. The buyers who regret theirs almost always made the same mistake: they fell for the interior photos before they checked the numbers. Here is the order to think about it.
1. Start with the truck you have, or the one you are willing to buy
Everything else follows from this. A loaded 32-foot gooseneck stacker can weigh 20,000 pounds with 4,000 of that on the hitch. That is a one-ton dually. A 24-foot bumper-pull stacker might come in under 14,000 loaded and tow behind a well-equipped three-quarter-ton.
Look at three numbers on your truck: the tow rating, the payload rating, and the rear axle rating. Payload is the one people miss. Hitch weight counts against payload, and so do passengers, fuel and everything in the bed. If the trailer's loaded hitch weight plus your crew exceeds payload, the truck is too small no matter what the tow rating says.
2. Gooseneck or bumper pull
Gooseneck puts the hitch over the truck's axle. The result is a trailer that tows flatter, resists sway better and turns tighter, which matters on a stacker because the upper deck puts weight high. The neck also adds storage or a sleeping loft. The cost is a truck with an open bed and a gooseneck ball.
Bumper pull works with more trucks, keeps the bed free, and is easier to hook and drop. For stackers up to about 28 feet it is the more common choice. Above 32 feet, almost everyone goes gooseneck.
3. Length: measure the cars, then add the shop
Measure your longest car bumper to bumper and add at least two feet for straps and clearance. That is the minimum deck length per car. Because the cars stack, trailer length is driven by one car plus whatever workspace you want in front of it.
- 24 feet: two cars, minimal walk-around, no real shop space. Lightest and easiest to tow.
- 28 feet: two cars plus a tool wall and cabinets. The most popular size for club racers.
- 32 feet: two cars plus a genuine work area, often a fridge and a bathroom.
- 36 feet and up: a rolling shop with living quarters. Triple axle, gooseneck, dually truck.
4. The lift: capacity, type and clearance
The lift is the part that makes a stacker a stacker, and it is where the money should go. Check three things. Capacity: the lift's rating should exceed your heaviest car by a comfortable margin, and remember that a car on a lift is a car's worth of weight on four cables or two cylinders. Type: hydraulic cylinder lifts and cable lifts both work; hydraulic is simpler to maintain, cable is lighter and often raises higher. Clearance: with the upper car raised, can you still stand up under it? Measure your lower car's roof height against the interior height minus the deck thickness. Many buyers discover too late that a tall car on the bottom makes the shop space unusable.
5. GVWR and payload
GVWR is the trailer's maximum legal weight loaded. Payload is GVWR minus the empty trailer weight, and it is the number that matters: two cars, fuel, tools, spares, a generator and a fridge add up faster than you expect. A 3,000-pound race car pair plus a reasonable amount of equipment needs 8,000 to 10,000 pounds of payload. All-aluminum trailers have a meaningful advantage here because the empty weight is lower.
6. Options that earn their keep
Not all options are equal. In roughly the order owners say they would pay for again:
- Electrical package with shore power and a generator. You will run lights, chargers, a fridge and tools at every event.
- Air conditioning. If you race in the South or in summer, this is not a luxury.
- Escape door. Getting out of a car on the lower deck with the upper car loaded is hard without one.
- Spread axles with brakes on all axles. Better tracking and much shorter stopping.
- Winch. For a car that does not run, or does not run well.
- Cabinets and a workbench. Nice, but these can be added later; the structural options cannot.
New or used
New gets you exactly the configuration you want and a factory warranty, at a price that starts in the high $40,000s and climbs past $150,000. Used stackers in good condition typically run $30,000 to $85,000. Aluminum does not rust and lifts are serviceable, so a well-kept used unit is a reasonable buy. Have the lift operated under load, check tire date codes rather than tread, and look at roof seams for water.
The short version
Truck first, then hitch type, then length, then lift. Get those four right and the rest is preference. If you want a second opinion on a specific unit, call us; we will tell you honestly whether it fits what you are towing with.
