Need a place to park! (Bastrop AREA (TOWARDS NB IS OK))

Hello! I'm a middle aged man looking for a place to park and live in my RV until I find property to purchase.
Ideally, I'd be happy to park on someone's property and maintain security in their absence.
I am a former Marine and dad, so I take commitments seriously.
I'm working nights in Bastrop and have only my son in NB anywhere nearby: so, the security of your property would be my only concern.
Thank You- Anthony
