South Carolina Camper Laws: Registration, Taxes, and Towing

South Carolina camper laws cover four things every owner has to get right: titling and registering the unit with the SCDMV, paying the state’s one-time infrastructure maintenance fee and annual county property taxes, carrying the correct insurance, and staying inside the state’s size, weight, and equipment rules on the road. The requirements split depending on whether you drive your rig or tow it, and public-land stays add their own limits on top.

Registration and Titling

Every camper and RV used on South Carolina roads has to be titled and registered with the SCDMV. You file Form 400, provide proof of ownership, and pay a $15 title fee. Proof of ownership for a new unit is the manufacturer’s certificate of origin; for a used one, it’s the previous title assigned to you. If no prior title exists, the SCDMV requires an Affidavit of Ownership (Form TI-021A) and a Vehicle Identification Verification (Form TI-021B).¹

Motorhomes register the same way a passenger car does, with a $40 biennial registration fee, and you’ll need proof of liability insurance before the SCDMV will process it.¹

Towable campers and travel trailers get their own Camper/Travel Trailer license plate at $10 every two years. The plate is required regardless of trailer weight. Before the SCDMV will issue registration, you have to pay personal property taxes on the trailer through your county.¹

If the unit is financed, the lienholder’s interest gets recorded on the title through South Carolina’s electronic lien and title system. The fee to record an electronic lien is $2.50.²

The Infrastructure Maintenance Fee

South Carolina does not charge a traditional sales tax on vehicles. Instead, every vehicle titled or registered in the state for the first time triggers a one-time infrastructure maintenance fee equal to 5% of the purchase price (or fair market value for private sales), capped at $500. The cap applies to both motorhomes and towable campers, and the SCDMV will not issue a title or registration until the fee has been paid.³

Several transfers are exempt, including transfers between immediate family members, transfers to a legal heir, and situations where sales or use tax was already paid on the transaction.⁴

Annual Property Taxes

South Carolina treats campers and motorhomes as personal property subject to annual county property taxes. You owe these taxes to your county, and you have to pay them before the SCDMV will renew your registration.¹

If your RV qualifies as a second residence, it may be taxed at the 6% assessment ratio rather than the standard personal property rate. To qualify, the unit generally needs to be used for camping and recreational travel, and the interest on any loan used to purchase it must be deductible as mortgage interest under the Internal Revenue Code.⁵

Insurance

Motorhomes need their own liability policy before the SCDMV will register them. South Carolina’s minimum liability coverage is $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $25,000 for property damage, and the state also requires uninsured motorist coverage at the same limits.⁶

Towable campers and travel trailers do not need a separate liability policy. The liability coverage on your tow vehicle extends to the trailer while you’re pulling it. Liability won’t pay for damage to the trailer itself, though. Protection against collision, theft, or weather damage to the camper requires adding comprehensive and collision coverage.

When You Need an Upgraded Driver’s License

Most RV owners can drive their rig on a standard South Carolina license. The threshold that changes things is 26,000 pounds gross vehicle weight. Above that, you need a Class E non-commercial license from the SCDMV. Class E is not a commercial driver’s license, so you don’t take CDL knowledge or skills tests, but you do have to qualify for the upgraded class.⁷

Business use is the exception. If you operate a motorhome over 26,000 pounds for commercial purposes, a CDL is required. Class E covers personal recreational use.⁷

Size, Weight, and Equipment on the Road

Dimensions

South Carolina caps vehicle width at 102 inches (8.5 feet) and height at 13 feet 6 inches. Combination vehicles (a tow vehicle plus trailer) cannot exceed 65 feet in total length.⁸

Exceeding any of these dimensions without a special permit from the South Carolina Department of Transportation can result in travel restrictions and citations. If your rig is close to the limits, measure before you hit the road.

Lighting and Brakes

Every RV and camper needs functioning brake lights, turn signals, and reflective markers. Trailers wider than 80 inches also need clearance lights and side markers.⁸

Brakes are required on any trailer or camp trailer with a gross weight of 3,000 pounds or more. Folding camp trailers and boat trailers in this range often use surge brake systems that activate independently from the tow vehicle. Motorcycle trailers are exempt unless they exceed 3,000 pounds gross.⁸

Towing Safety

Every towed trailer has to be attached to the tow vehicle by a safety chain or cable in addition to the primary hitch. This backup connection prevents separation if the main coupler fails.⁹

Your tow vehicle also needs mirrors that give an unobstructed view behind the trailer.

Speed and the Move Over Law

RVs and campers follow the same posted speed limits as passenger vehicles, and slower-moving rigs should stay in the right lane on multi-lane highways except when passing. South Carolina’s Move Over law requires drivers to change lanes or slow down when approaching any stopped emergency vehicle, tow truck, or roadside service vehicle displaying flashing lights. If changing lanes isn’t safe, you must reduce speed and proceed with caution.¹⁰

Weight Limits

On interstates, a single axle cannot exceed 20,000 pounds, a tandem axle is limited to 35,200 pounds (including enforcement tolerances), and overall gross weight tops out at 80,000 pounds under the federal bridge formula. On non-interstate highways, tandem axle limits can reach 36,000 pounds. Exceeding these without a special overweight permit can result in citations.¹¹

Most recreational setups won’t approach these thresholds, but owners of large Class A motorhomes towing a second vehicle should verify their gross combined weight stays within both manufacturer ratings and legal limits.

Parking and Overnight Stops

Many South Carolina cities restrict how long an RV can sit on a public street, with 24- to 48-hour limits common in municipalities like Charleston and Columbia. Vehicles left beyond those limits risk being towed at the owner’s expense. Homeowners’ associations often go further, requiring RVs to be stored out of sight or inside enclosed structures.

The South Carolina Department of Transportation permits RVs to stop at designated rest areas, but overnight parking is generally not allowed. Some commercial lots, particularly certain Walmart and Cracker Barrel locations, may allow overnight stays at the property owner’s discretion, though local ordinances can override that permission. Beach-access lots in tourist areas like Myrtle Beach frequently restrict oversized vehicles.

Camping Stay Limits on Public Land

State Parks

South Carolina’s state parks offer designated RV camping areas with electrical hookups and dump stations at many locations. Reservations can be made up to 13 months in advance, and the maximum stay at any single site is 14 nights.¹²

RVs must park within designated sites, and generator use may be restricted during quiet hours. Dumping wastewater outside approved disposal stations is a serious offense. Using state park facilities without authorization is treated as trespass and can carry a fine of up to $5,000, imprisonment for up to two years, or both.¹³

National Forests

Dispersed camping in areas like the Francis Marion National Forest is allowed in certain zones without a reservation. Camps must be set up at least 50 feet from water and trails, and at least half a mile from any road or parking lot.¹⁴

The stay limit for dispersed camping on national forest land is 14 days within any 30-day period.¹⁵

Penalties

Enforcement runs across state park rangers, local police, and the South Carolina Highway Patrol. Operating an unregistered or improperly titled RV can result in fines and possible impoundment. Towing violations, including exceeding weight limits or failing to use a safety chain, can lead to citations, and serious violations may require a court appearance. An RV or camper that causes an accident because of equipment noncompliance exposes the driver to civil liability on top of any traffic penalty.

The harshest penalties involve state park trespass and illegal dumping, where a violation is punishable by a fine of up to $5,000, imprisonment for up to two years, or both.¹³ Municipal parking violations typically carry lower fines set by local ordinance, but repeat violations or ignored citations can escalate to towing and impound fees. Confirming registration, insurance, and equipment before each trip is the simplest way to stay clear of all of it.
