Can we park our rv there in the parking lot for overnight stay?

Can we park an 18 wheweer in a tv park

Let me answer this in the best way possible: if you are TRANSPORTING an RV between point A and point B, under a DOT authority, then yes. Otherwise GTFO of a space that a professional driver is going to need!

I recommend not to eyesore the place by not doing so. Looks like there is a lot of open space to the south

I have seen many in the past...
