I too have seen people do this. Especially in the spring and fall here in NE. The CG's offer these 6 week packages were you can leave your RV on site and use during the weekend (different than seasonal I know). People with pop ups participate and leave them set up for the full 6 weeks.
To me i would not like it as I think it just puts more abuse from the elements on the tenting and unit. It may be a good idea to put some Gizmos over the tenting to protect.
Jersey shore sounds great! I love camping by the beach. We visit every year in Maine at the beaches.
