Enclosed Cargo Trailer Buyer’s Guide: Single Axle vs. Tandem, V-Nose vs. Flat, and the Features Worth Paying For, From Grizzly Trailer Sales
An enclosed cargo trailer is one of those purchases that gets used harder and longer than buyers expect. The 6×12 someone bought for a couple of motorcycles ends up hauling tools for a side business three years later. The 7×14 a contractor bought for a remodel job became a mobile workshop for a decade. Picking the right size and configuration up front is worth more than the price difference between models, because resale and upgrades both cost money you didn’t plan to spend. Grizzly Trailer Sales walks buyers through this decision regularly at our Rupert and Montpelier lots, and a few specific choices determine whether the trailer earns its keep or just sits in the driveway.
This is the first fork in the road and the one most buyers underestimate. The choice changes towing feel, payload, tire wear, and what you can realistically do with the trailer.
Single axle trailers are lighter, easier to maneuver, and cheaper. Common sizes run from 4×6 up through 6×12 and occasionally 7×14. Backing one into a tight space, hand-pushing it around a garage, and tucking it into a storage spot are all easier with a single axle.
The trade-offs are real. Single axles typically max out at 2,990 GVWR to stay under the Idaho titling and brake thresholds, which limits payload to roughly 1,500 to 2,000 pounds depending on the trailer’s empty weight. A single blown tire on a single axle trailer drags the rim and cargo on the pavement until you can stop, often damaging the trailer.
Tandem axle trailers spread the load across two axles. Common sizes run from 6×12 up through 8.5×24 and beyond. GVWRs typically start at 7,000 pounds and go up from there. Payloads in the 4,000 to 5,000 pound range are common.
What tandem axles get you:
- Better stability at highway speed
- Significantly more payload capacity
- Brakes on at least one axle in most configurations, required by Idaho Code § 49-927 above the weight threshold
- A second tire that keeps the trailer rolling if the first goes flat
- Better resale value for most use cases
The honest rule: single axle is fine for occasional, lighter use. Anyone hauling tools daily, planning to grow into the trailer, or running highway miles regularly should plan on tandem.
V-Nose vs. Flat Front
The V-nose has become the default in most enclosed cargo lines, but flat-front trailers still have their place.
V-nose front ends extend the trailer by about 24 to 30 inches at a point. The angle reduces wind resistance at highway speed, adds enclosed storage space in the nose, and tends to look more refined. The extra interior volume often becomes shelving, a workbench, or storage for racing gear, fishing equipment, or contractor supplies.
Flat front trailers give you the full rectangular interior with no triangular dead space at the front. Maximum usable cargo length matches the exterior length more closely. Flat fronts also tend to cost slightly less.
For most buyers, V-nose is the better choice. The fuel savings over years of towing typically more than cover the price difference, and the extra storage volume is genuinely useful. Buyers hauling specific cargo lengths that need maximum rectangular interior space, or those on tight budgets, may still prefer flat front.
Ramp Door vs. Barn Doors
The rear door style affects how the trailer gets loaded and what fits inside.
Ramp doors are a single hinged door that lowers to the ground and creates a built-in loading ramp. Loading motorcycles, lawnmowers, side-by-sides, snowmobiles, and rolling carts is significantly easier. The ramp door also seals more tightly against weather when properly maintained.
Barn doors are double doors that swing open on side hinges. They allow forklift loading, are easier to open in tight spaces where a ramp wouldn’t have room to lower, and provide better access for moving large rigid objects in and out. Construction crews and movers often prefer barn doors for this reason.
For ATV, motorcycle, side-by-side, and equipment hauling, ramp doors are usually the right call. For stationary tool storage, mobile workshops, and contractor use where the trailer rarely needs roll-in loading, barn doors work fine.
Interior Height and Width Choices
Standard interior height on a 6-foot or 7-foot wide cargo trailer typically runs 6’3″ to 6’6″. Many trailers offer additional height upgrades to 7′ or taller. Anyone over 5’10” who plans to work inside the trailer regularly will appreciate the extra clearance.
Width affects what fits side by side. Standard widths are 5′, 6′, 7′, 8.5′. The jump from 7-foot to 8.5-foot is the most significant in terms of what you can park inside. A 7-foot wide trailer fits most side-by-sides and ATVs. An 8.5-foot wide trailer accommodates two-place ATV setups, smaller cars, and most full-size motorcycles parked sideways.
Features Actually Worth Paying For
After enough conversations on the lot, the features that hold real long-term value become clear:
- Aluminum wheels over white spokes: better corrosion resistance, easier cleaning, improved resale
- Side door with RV-style flush latch and screen door option: dramatically increases usability for any in-trailer work
- Roof vent with fan: prevents condensation, keeps interior temperatures manageable, useful for any organic cargo
- Interior LED lighting: minimal upgrade cost, significant practical value
- 12V battery and exterior outlet: turns the trailer into a workable mobile shop
- Plywood walls instead of bare metal interior: allows hanging hooks, shelves, and racks anywhere
- Torsion axles over leaf spring: smoother ride, lower maintenance, longer life
- Upgraded floor with rubber coin or seamless coating: protects the plywood and extends trailer life significantly
Features that often don’t earn back their cost: chrome trim packages, custom paint schemes, oversized stereo systems, and decorative LED light strips. They look good initially and rarely affect resale value meaningfully.

How Grizzly Trailer Sales Helps Buyers Match Size to Use
The 15-minute conversation that gets buyers to the right enclosed trailer usually covers what’s going inside, what truck is pulling it, where it’s getting stored, and how often it’ll be on the highway. From there, the right size, axle configuration, door style, and feature package falls into place. Our lots stock enclosed cargo trailers from manufacturers known for solid construction and reasonable warranties.
Stop by 305 W 100 S in Rupert or 740 N 4th St in Montpelier to walk through our enclosed cargo inventory in person, or call Grizzly Trailer Sales at (208) 678-2981 to talk through which configuration fits what you’re actually hauling. The right trailer purchased once is far cheaper than the wrong one bought twice.
