Yes, but once you're on the Island, things get a little more interesting. It may a look a bit out-of-the-way, but I'd suggest taking the LIE(495) to the Seaford-Oyster Bay Expressway (Rt. 135). That will give you the quickest route to the South Shore. Your alternative is surface streets.
The S-OB ends at Merrick Rd (also known as Montauk Hwy). A short drive back west on Merrick Rd will get you to the Wantagh Parkway and down to Jones Beach.
Trucks/RVs are ok to travel on both the Meadowbrook and Wantagh Parkways south of Merrick Rd.
ETA: Spent the first 22 years of my life on Long Island - going to the Jones/Moses beaches every weekend during the summer was SOP for us.
ETAA: There are still some low bridges once you get to Jones Beach. You can use Google Maps Street View and you can see the bridge clearance signs. There's one 8-foot bridge, which you can go around, but then there's a 12' bridge.
They obviously can get semis down there for all the concerts they do at Jones Beach Theatre, so there must be a way. You might actually have to go further east to the Robert Moses Causeway, and come back west on Ocean Parkway.
