If you have an RV 17 foot Jayco Trailer can you also accommodate a 6 man tent?

There was an RV in the space next us that had their kids staying in a tent. (It looked like a 2-person.) Some of the spots have grass between them. They were there several days, and it didn't seem that the RV staff minded. There certainly should be room behind a 17' trailer, but a 6-person tent would probably have to go on the cement, so bring air mattresses.

There are no tents allowed in spots, its like parking lot spaces but they do have 2 tent sites near the restroom with its own bbq area
