Towing Capacity, Tongue Weight & Setup
First Time Towing a Trailer
Everything takes longer and needs more room. Nothing about it is difficult once you expect it.

Short answer
Braking distances grow, turns need to be taken wider, reversing is mirrored, and crosswinds matter. Leave more gap, slow earlier, and practice reversing in an empty lot before you need to do it at a campsite.
What actually changes
| What | How it changes |
|---|---|
| Braking | Longer - start earlier and leave much more gap |
| Turning | The trailer cuts the corner - swing wider than feels right |
| Reversing | Steering input is mirrored; small inputs, early corrections |
| Overtaking | Needs far more room and much more patience |
| Crosswind and passing trucks | A real, physical push - expect it at bridges and gaps |
| Hills | Slower up; use lower gears down rather than riding the brakes |
| Fuel stops | Plan them - a long rig does not fit every forecourt |
Before you leave
- Coupler seated, latched and pinned. Look at it, do not assume it.
- Chains crossed under the coupler. So they cradle it if the ball lets go.
- Breakaway cable to the vehicle, not to the safety chains.
- Lights checked. Running, left, right, brake. Get someone to watch, or use a reflective surface.
- Tongue weight in range. 10 to 15 percent of loaded trailer weight.
- Tires at the right pressures, trailer and tow vehicle, measured cold.
- Jack fully raised and the handle stowed.
- Chocks removed last, after everything else is connected.
Practice reversing before you need it
An empty parking lot, a couple of cones or cardboard boxes, and half an hour. The technique that makes it click for most people: put your hand at the bottom of the steering wheel, and move it in the direction you want the trailer's back end to go. Small inputs, and correct early - a trailer that has started to jackknife needs you to pull forward and start again, which is normal rather than a failure.

1. Buy before the first trip
Camco Trailer Wheel Chocks
Camco · Best for every trailer, without exception
Chocks go in before you unhitch, every time. They are not an upgrade and they are not interesting; they are the thing standing between a parked trailer and a slow roll down a campground slope.
We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.
What works
- Cheap insurance against the most preventable trailer accident there is
- Works on any trailer regardless of brakes or jack type
- Takes seconds and needs no setup
What does not
- Plastic chocks degrade in sun over several seasons
- Easy to leave behind at a site
Skip it if
There is no situation where you should skip chocks - if these do not suit your tire size, buy different ones rather than none.

2. Start right
Sherline Trailer Tongue Weight Scale
Sherline · Best for measuring tongue weight at home
A dedicated scale you sit under the coupler to read tongue weight directly, with no arithmetic and no trip to a weighbridge. It is the one tool on this site that turns the single most important towing number from a guess into a measurement.
We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.
What works
- Direct reading, with no bathroom-scale-and-lever arithmetic
- Repeatable, so you can see what moving the load actually does
- Mechanical gauge with no batteries to be flat when you need it
What does not
- Must be used on level ground with the coupler at towing height
- Single-purpose tool that spends most of its life in a cupboard
Skip it if
Unnecessary if your hitch already has a built-in gauge, or if you have a public scale nearby and are happy to use it.

3. If the trailer is wider
K Source Universal Clip-On Towing Mirror
K Source · Best for occasional towing with a wide trailer
Straps over the existing mirror to extend the view past a wide trailer. The honest limitation of every clip-on is vibration: they work, they are legal where extension is required, and they will never be as steady as a replacement mirror.
We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.
What works
- Fits almost any vehicle and transfers between them
- Removable, so the vehicle looks standard the rest of the year
- Far cheaper than replacement mirrors
What does not
- Vibration at highway speed blurs the view, which is worst on rough surfaces
- Straps mark paint and mirror housings if grit gets underneath
Skip it if
Not the one if you tow weekly - the daily on-off routine gets old fast and replacement mirrors stay aligned.

Key takeaways
- Everything needs more distance and more time - plan for it rather than reacting.
- Swing wider on turns; the trailer tracks inside your line.
- Practice reversing somewhere empty before it matters.
- The pre-departure checklist prevents most first-trip problems.
How we sourced this
Every figure on this page came from one of the following, each fetched while the page was written. Where a manufacturer or regulator does not publish a number, we say so rather than estimate it.
Common questions
- How fast should I drive when towing?
- Below the speed where the rig feels busy, and within any towing speed limit your state applies - several set a lower limit for vehicles with trailers. Many trailer tires also carry a speed rating lower than you would expect.
- Do I need a special license?
- For most private trailers, no - but requirements vary by state and by combined weight. Check your own state's rules, particularly above the heavier thresholds.
- What is the hardest part?
- Reversing, and then only until it clicks. Half an hour in an empty lot is worth more than any amount of reading.
