Never had a problem in any RV park gated or not, or felt unsafe even in some "rough" areas
Have done several Wally world's, truck stops, rest areas, and other spots of opportunity.
In these locations ....
use common sense
never out of arms reach of your phone
don,t exit the rig (especially after dark) without checking your surroundings
don't leave your steps down (bad guys can't see in or get a good grip on handles or locks.
If you get a knock after your in bed you can do several things. Ignore it 911 or in the 2 times this has happened to me I turn on my lights keep inside lights off, open a side window and tell them to step into the lights and will talk (You can also at say mostly out the window Honey hand me the shotgun)He/she ran
Never open the door ever.
On the second time the response from outside was "State Police" My response was again step into the light. Full uniform dude, again out the side window "calling 911 your name and badge please sorry just need to verify" All good, turned the interior lights opened the door and found out I was wrong to park there.
Apologized an the tropper who said "OK to be careful"
Life is meant to be lived and is never without some risk!
