The plan is simple: back a boat down the double-sided concrete ramp at St. Andrews State Park, find a trailer-length spot in the lot before the summer crowds claim them, and spend the day on Grand Lagoon. Whether that actually goes smoothly depends almost entirely on which used heavy-duty truck you're driving.
A well-chosen used Ram 2500 from the right model years handles all of it with room to spare. The tricky part is knowing which years to target and which to skip -- and that decision matters more for a used HD truck than for almost any other vehicle.
What's the plan at a glance?
| Stop | What to do | Best time to arrive | Parking note |
|---|---|---|---|
| Park entrance off Thomas Drive | Pay day-use fee, grab a trail map | Before 9 a.m. in summer | Single-lane entrance; big trucks need patience |
| Boat ramp (Grand Lagoon side) | Launch via the double-sided concrete ramp | Early morning | Overflow lot for trailers when ramp lot fills |
| Jetty Beach | Swim, fish from the jetty rocks, snorkel the lagoon | Midday to late afternoon | Walk from main beach lot; no trailer parking here |
| Gator Lake overlook | Short walk, wildlife viewing | Any time | Park in the main lot and walk the easy trail |
| Shell Island ferry dock | Catch the shuttle to Shell Island | Morning (tickets sell out) | Truck stays at the ramp-side lot |
The Boat Ramp Is the Real Test
The Florida State Parks website confirms that St. Andrews State Park's boat ramp is a double-sided concrete launch that accommodates the smallest to the largest of watercraft -- but that generous ramp gets genuinely crowded on summer mornings. Getting your rig in and out cleanly, on the first try, in front of a line of impatient anglers, is where a well-maintained used HD truck either earns its keep or embarrasses you.
That means you want a truck with a proven integrated trailer brake controller, tow mirrors wide enough to see the trailer corners, and a powertrain that doesn't shudder under a loaded trailer at low ramp speeds. All three are standard or widely available on mid-2010s and newer HD trucks. What varies -- and what the used-truck market does not always tell you clearly -- is which specific model years deliver those things reliably and which ones carry known headaches.
A used Ford F-250 from the 2020-2021 generation, for example, introduced the 7.3L "Godzilla" pushrod gas V8 producing 430 horsepower -- a near-zero early complaint record makes it one of the most dependable Super Duty configurations for buyers who want a gasoline engine without diesel maintenance complexity. That's useful information. Knowing the 2003-2007 6.0L Power Stroke era requires documented bulletproof repairs before it's trustworthy is equally useful.
Three Truck Families Worth Shopping Used
Thomas Drive runs straight from Panama City to the park entrance, and on any given Saturday morning it's a parade of HD trucks and trailers headed the same direction. Here's how the three most common used heavy-duty truck families stack up for that specific errand, based on verified model-year reliability data.
Ram 2500 and Ram 3500. The 6.7L Cummins turbodiesel block itself is one of the most durable diesel engines in the pickup segment, with documented examples surpassing 300,000 miles on routine maintenance. What tends to fail is the emissions equipment -- the DEF injector, the DPF filter, and on high-load builds, the standard 68RFE automatic transmission. The 2016-2018 Ram 2500 with the High Output Cummins and Aisin transmission represents one of the strongest mid-price used HD buys available right now: the emissions systems had been refined, the Aisin handles sustained towing loads significantly better than the 68RFE, and complaint volume is low. The 2020-2022 Ram 2500 introduced the High Output Cummins at 1,000 lb-ft of torque and brought NHTSA complaint volume to the lowest of any modern Ram 2500 era -- a solid target if you want the newest-generation interior. Skip the 2013 Ram 2500 without a specific inspection for the intake plenum bolt, and avoid the 2011-2012 range outright due to DEF and DPF failures plus documented tie-rod issues.
Used Ram 3500 trucks follow a similar pattern: the 2017-2020 generation with the 6.7L Cummins is generally considered excellent for heavy trailers when maintained on schedule, and the 2020+ High Output version delivers class-leading towing when properly equipped.
Ford F-250 and F-350. Engine choice determines reliability more than model year in the Super Duty line. The 6.7L Power Stroke diesel from 2015-2016 is the diesel sweet spot of the third generation -- refined enough to be dependable, old enough to have significant depreciation. The 2020-2021 F-250 with the 7.3L gas V8 is the safest used Super Duty buy for buyers who want simplicity: NHTSA complaint volume for those years is among the lowest in the model's modern history. Avoid the 2003-2007 6.0L Power Stroke without verified bulletproof repairs, and give the 2008 6.4L a wide berth regardless.
Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD. For diesel buyers, the 2017-2019 Silverado 2500 HD range with the L5P Duramax is the primary recommendation -- you get the strongest diesel in the K2XX generation. For buyers who want the current-generation platform, the 2021-2023 T1XX examples represent the generation at its most refined; the 2020 first-year T1XX had early transmission calibration feedback that was addressed in subsequent years. Avoid the 2003-2006 mid-2000s Silverado 2500 HD range, which generates the highest owner complaint volume of any modern generation.

What to Check Before You Buy for Gulf Coast Use
Salt air is the hidden variable in any Panhandle used-truck purchase. Panama City's coastal environment accelerates corrosion on brake lines, undercarriage components, and trailer hitch hardware. A truck that spent its working life in the Midwest may look clean underneath; one that's hauled boats in Bay County for years is a different inspection checklist entirely.
- Check brake lines and hitch receiver for surface rust and pitting, not just dirt
- On any used Cummins, pull the DEF fluid for clarity and test injection pressure before buying
- On 6.7L Power Stroke trucks, look for signs of coolant contamination and EGR service history
- On Duramax trucks, verify the DEF heater and NOx sensor function to avoid limp-mode surprises
- Confirm integrated trailer brake controller is present and functional -- it's a real-world need at the St. Andrews ramp
- High mileage is not automatically a dealbreaker on a diesel; clean service records and tight steering over bumps matter more than the odometer reading
The Truck Completes the Trip
St. Andrews State Park sits on 1,200 acres between the Gulf of Mexico and St. Andrews Bay, with over 1.5 miles of beach, two fishing piers, a jetty, nature trails through coastal plant communities, and a ferry shuttle to Shell Island. The park is open 365 days a year from 8 a.m. to sundown. Summer is busy and beautiful; the shoulder months of October and November offer the same emerald water with far fewer people at the ramp.
A used heavy-duty truck makes all of it more possible -- hauling the boat down Thomas Drive, launching without drama, towing the kayaks out for the afternoon. The Bay Cars team at 615 W. 15th St. in Panama City carries a rotating selection of pre-owned HD trucks across multiple makes and model years. Knowing your target year range before you walk the lot puts you ahead of most shoppers.
