Major access to Smithtown comes via the Long Island Expressway (I-495), with Exit 56 (Route 111) providing the most direct route into town. Route 25 (Jericho Turnpike) runs east-west through the center of Smithtown, connecting to most local dump stations. RVers should note that many Long Island roads have low overpasses, particularly on parkways which prohibit commercial vehicles and large RVs.
Avoid the Northern State Parkway and Southern State Parkway entirely in your RV -- these have bridge clearances as low as 8 feet in some sections. Stick to Route 25, Route 111, and other numbered routes for safe passage. The area's suburban layout means narrow residential streets, so plan your route carefully to avoid getting stuck in neighborhoods not designed for RV traffic.
Overnight parking options are extremely limited in this densely populated area. Most Walmart stores on Long Island don't allow overnight RV parking due to local ordinances. Your best bet for overnight stays involves booking at established campgrounds or RV parks in nearby areas like Wildwood State Park to the north.

Blydenburgh County Park's dump station gets busy during camping season, so weekday visits work better than weekends. Bring your own rinse water since not all stations provide adequate water pressure for thorough tank cleaning.
Stock up on supplies at the Home Depot on Route 111 or the Lowe's on Jericho Turnpike -- both carry RV basics like hoses and fittings if you need replacements. For propane fills, try U-Haul locations or hardware stores rather than gas stations, which often don't service RV tanks.

Plan extra time for navigation since GPS systems sometimes route RVs onto restricted parkways. Keep a Long Island road atlas handy and double-check your route before moving.
