Can a Kia Sportage Tow a Small RV? The Complete Weight & Physics Analysis

"Small RV" covers three quite different trailers:

• Teardrops and small square-drops: sleep-only or with a rear galley. Many are under about 1,500 lb loaded.
• Small fiberglass and stand-up trailers (13–17 ft): a bed, a dinette and often a small kitchen. Loaded weights commonly run from the high 1,000s to well over 2,500 lb.
• Compact conventional travel trailers: even the shortest often carry GVWRs above 3,000 lb.

Those ranges are planning approximations, not manufacturer specifications. What decides it is your trailer's GVWR from its data plate, or a scale weight, never the brochure's dry weight. See dry weight vs GVWR.

Verdict:

• Gas Sportage: teardrops and the lightest stand-up trailers. With working brakes, plan around 1,800 lb loaded at a 12% tongue (inside both the 220-lb tongue limit and the 80% planning figure of 2,000 lb).
• Hybrid and plug-in: the same tongue math, with an 80% planning figure of 1,600 lb.
• Unbraked trailers on any Sportage: 1,653 lb maximum, about 1,320 lb at the 80% planning figure.
• Compact conventional travel trailers: generally out of reach.

Kia's 1,653-lb unbraked limit applies regardless of where you drive. Above it, the trailer must have working brakes, which for electric brakes means fitting a brake controller in the Sportage.

State law can be stricter. Some states require trailer brakes at weights below 1,653 lb, and the rules for breakaway systems differ too. The state-by-state brake chart shows where the thresholds sit; each state's page in the towing laws directory has the statute.

See our brake controller guide for choosing and setting one.

Kia lists GVWRs of 4,674 lb (FWD) and 4,850 lb (AWD) for the gas Sportage, 4,751–4,949 lb for the hybrid and 5,335 lb for the plug-in. Curb weights vary by trim, so the payload for your vehicle is the figure on its door label, not a number you can work out from the brochure.

Hypothetical example of the arithmetic:

• Payload on the label: 1,040 lb
• Two adults and a child: 415 lb
• Dog: 65 lb
• Cargo, including a roof box: 165 lb
• Ball mount: 15 lb
• Payload left over: 1,040 - 660 = 380 lb

Payload has room for 380 lb, but Kia's tongue limit is 220 lb. On a Sportage, payload is rarely the binding number for a small trailer; the 220-lb tongue limit is. Read more in payload vs towing capacity.

All numbers are invented to illustrate the method.

A 2025 Sportage 2.5L AWD (2,500 lb braked, 1,653 lb unbraked, 220-lb tongue) with a hypothetical door-label payload of 1,005 lb, and a teardrop with no brakes, a dry weight of 1,269 lb and a GVWR of 1,600 lb.

Trailer: 1,269 lb plus a battery, propane and camping gear (190 lb) = 1,459 lb.

• Which Kia figure applies: no brakes, so 1,653 lb. The teardrop is at 88% of it, above the 1,322-lb (80%) planning line.
• Tongue at 11.5%: about 168 lb, inside the 220-lb limit.
• Payload: two adults (335 lb), cargo (85 lb), ball mount (45 lb) = 465 lb; plus 168 lb tongue = 633 lb, inside 1,005 lb.

This combination is legal against Kia's limits but has little margin on the unbraked rating. Moving some gear into the Sportage (it has payload to spare) or choosing a teardrop with brakes, which lifts the applicable limit to 2,500 lb, both fix that.

Now try a 2,300-lb stand-up trailer with brakes: under the 2,500-lb rating, but a 12% tongue is 276 lb, which is 56 lb over the 220-lb limit. That is the Sportage pattern.
