We own the lot across the street from our seasonal restaurant Back Bay BBQ, https://backbaybbq.com/. We allow people to stay on the lot for a day or two. You can fill the water tank and can dump the holding tank though the location for the dump is sloped. We have a 40 DP and are often there. The lot is next to Route 152 in the middle of the causeway to Atlantic City / Ocean City.
Our restaurant closes at 9:00 PM so we like peace and quiet after that; it is a residential neighborhood. No open fires as we are in the salt marshes.
Large level gravel parking area.
Gravel parking area next to or near rig.
Atlantic Ocean and Great Egg Harbor are right down the road. The inlet has Malibu Beach which is very popular as it is dog friendly. Atlantic City and Ocean City are minutes away.
