The 2026 Chevrolet Suburban is genuinely built for what Grand Strand families ask of it every summer. Load eight people, every suitcase, maybe a trailer, then put 600 or 800 miles behind you in a single day. It can do all of that. What trips people up is that leaving Myrtle Beach in August takes a little more strategy than pointing the nose toward I-95, and the Suburban rewards a driver who understands its systems instead of trusting it to sort things out.
Below is the short version our team at Palmetto Chevrolet runs through before you’re loaded up and rolling out of Conway or the Grand Strand.
Do’s and Don’ts for a Long-Haul Suburban Trip
The moves in the table below are the ones that actually change your day, and most of them are small, so skipping any single one on a cool morning probably costs you nothing, while skipping two or three together on a hot August Saturday is how a family ends up parked on an I-95 shoulder instead of a mountain cabin. Read it before you load the truck.
| Situation | Do | Don’t |
|---|---|---|
| Departing the Grand Strand | Leave before 10 a.m. or after 7 p.m. Take SC-22 to SC-31 (Carolina Bays Parkway) to bypass Conway congestion | Attempt US-501 eastbound on a Saturday afternoon between noon and 5 p.m. |
| I-95 speed | Set cruise at the 70 mph limit in South Carolina; ease to 65 through the Lumberton, NC curves | Speed past the state line. South Carolina Highway Patrol is notoriously active on I-95 near the NC border. |
| Fuel stops | Fill the 28-gallon tank before you leave. The diesel Suburban carries up to 728 miles of EPA-estimated highway range per tank. The V8 trims get roughly 19-20 mpg on the highway | Let the fuel gauge drop below a quarter tank on rural I-95 stretches. Service areas thin out between Florence and the NC Welcome Center |
| Tire pressure + load | Check cold tire pressure before loading. A full passenger load plus luggage shifts weight to the rear axle | Assume the tires are fine because they looked fine last weekend |
| Trailer or camper | Verify your actual tow rating on the door-jamb sticker. The 5.3L V8 is rated up to 8,200 lbs when properly equipped (confirm via your build sheet) | Use the class maximum figure as your personal maximum without checking your specific vehicle’s placard |
| Cabin temperature | Pre-cool the interior while still parked. The Suburban’s tri-zone climate can hold a comfortable temperature at highway speed with less A/C load | Blast the A/C from a scorching standstill. It drags highway fuel economy noticeably on V8 trims. |
| Tech | Enable available Super Cruise on compatible highway stretches to reduce driver fatigue on long flat I-95 sections | Use hands-free tech as permission to stop paying attention. It still requires eyes on the road |
| Night driving | Use the available head-up display to keep your eyes forward in low-light conditions | Drive fatigued. Pull over. The Suburban will still be there when you wake up |
The One Thing That Matters Most: Leave on the Right Route at the Right Time
Your route out of town and your departure time decide whether the trip starts smooth or starts stuck, more than any other single choice you’ll make that morning, because US-501 is the obvious artery from Myrtle Beach toward I-95 through Conway, and on a summer Saturday afternoon it can stretch a 90-minute drive to the interstate into a two-and-a-half-hour crawl. We know it, visitors know it, and people still leave at 2 p.m. on a Saturday in August.
Take SC-22 (the Conway Bypass) to SC-31 (Carolina Bays Parkway). SC-31 runs as a limited-access highway alongside the Intracoastal Waterway, heading west without a single traffic light until it ties into SC-544. From there you slide onto I-95 at Florence and skip the US-501 tourist drain entirely. It adds roughly ten minutes over a theoretical direct shot, and it spares you the standstill everyone else creates by running the same math at the same time.
Once you’re on I-95, north or south, the Suburban settles in beautifully. Diesel-equipped trims give you a Duramax 3.0L pulling 495 lb-ft of torque at 2,750 rpm, and the EPA puts highway fuel economy at 26 mpg (RWD) or 24 mpg (4WD). Pair that with the 28-gallon tank and you land on Chevrolet’s stated 728-mile highway range. On the diesel you can leave Conway and pass through Florence, Santee, Columbia, Charlotte, Statesville, Wytheville, and be closing in on the Virginia-West Virginia line before you need fuel. V8 buyers should plan stops every 400 to 450 miles based on 19-20 mpg highway.
A pre-trip service check before you leave is never wasted on a big run. Fresh oil, a correct coolant level, and cold tire pressure take about twenty minutes and pull a lot of uncertainty out of an 800-mile day.
The Chevy Tahoe is worth a mention here as a comparison point, since it shares the same powertrain family. What sets the Suburban apart is its 16 additional inches of length behind the third row, which means you carry real luggage without folding seats. You get 41.5 cubic feet of cargo space with all three rows occupied (enough for actual suitcases and a stroller without an argument).
Keep Everyone Comfortable and Stay Aware
Long trips reward preparation over willpower, so the comfort you set up before you roll matters more than the toughness you try to summon at mile 400, especially with a full third row of kids and a low-country sun loading the cabin from every angle. Small habits carry the day here.
The Suburban’s third row offers 36.7 inches of legroom, per Chevrolet’s specifications, and that number holds up in person instead of reading like brochure math. Plan a stop every 90 minutes when kids ride back there, no matter how roomy it feels. Kids need to move. The I-95 North Carolina Welcome Center near the state line keeps clean facilities and covered parking. Kenly 95 Travel Plaza gives you amenities without leaving the interstate corridor at all.
Comfort systems for an August drive:
- Available ventilated front seats and rear-row climate controls help when the SC low country sun loads the cabin from every angle.
- Pre-cooling the Suburban while it’s still in the shade lets the system hold temperature efficiently at 70-75 mph.
- The efficiency hit is measurably lower than clawing your way down from a 100-degree interior.
Check the National Weather Service forecast for the full corridor before you depart, and don’t stop at the Myrtle Beach beach forecast. South Carolina summer heat runs hot, and the Grand Strand sits close to hurricane-track weather, so the sky over the sand tells you very little about the sky over I-95. An I-95 thunderstorm between Florence and Santee is a different animal than afternoon clouds at the beach.
Our Chevy Traverse serves families who need three rows in a smaller, more maneuverable package. But if your crew fills all three rows and you’ve got beach gear to haul, the Suburban is the honest answer. There’s no substituting for 144.5 cubic feet of maximum cargo volume when everyone’s bringing actual luggage.
Your 2026 Suburban’s ready for wherever US-501 and I-95 take you. Schedule a Pre-Trip Service Check before a long run, and our service team’ll make sure everything’s ready to go.
