We do try to take precautions on the road some might think extreme till they get broken into. At SnB we are just like Crasher with keys in trucks, RV left open, doors open when we go out for couple hours here and there. Maybe we are too naive for our own good but..........
Only ever had one problem in 15 years of RVing: Heard a noise at back of RV when in bed one night around 12.30am boondocking in Kelowna BC large open car park of stores. I snuck up to drivers seat pressed on rear view camera and saw the guy trying to undo locks on seadoo hitched to RV. Went and woke hubby trying to keep him quiet (not easy when woken up!), told him. He grabbed 4 ft wooden table support pole by door, ran out in his underwear bless him, and guy ran off. Less than a minute later a buddy turned up in car with cutters but they both hightailed it as by then engines were started and we were headed to find a group of RVers at good old Walmart (now you know why other RVers group in numbers LOL). Guess I was easily woken because I never felt comfortable where we'd stopped in the first place and didn't want another tiff with hubby to find somewhere else after saying 4 other places he wanted to pull in were no good.
We hadn't been to Kelowna for about 9 years, and remembered a great safe feeling place. However on that last trip there we noticed the people seemed to have changed, the overall impression had changed and that all Jewellery stores were locked and had doorbells on them to gain entry.
Not sure how true this is but ........We were told by locals that Vancouver had offered a deal to a lot of homeless and shipped them up to Kelowna in bus loads and that's when their problems started. Just sharing what we were told whether true or not.
Precautions = For personal safety: trust my gut feeling before stopping anywhere always, even if it means driving further on than we want to - hubby now agrees for the mostpart as I wouldn't sleep worrying. Try to locate ourselves where there are other RVers generally in number except when rustic boon docking where we're likely to be not far from the Rig and it's highly unlikely an opportunitist will head that far out from civilization to do anything
Precautions For Theft: Pull down day blinds, leave something with noise on if possible, hide or secure back in bays anything that's a quick easy sweep. Split our monies, any jewellery or small valuables into four or five different sets and hide all over the RV in least expected areas, (ie; ziplock in bottom sugar/coffee jars, in pillow covers, taped under seats - so heaven forbid they find one or two they might not find the lot. Never leave the two sets of keys in view.
Odd times we stay in actual campgrounds ask at check in any problems with theft, break in's any wildlife precautions, anything we need to be aware of. San Diego said lock everything down theft mainly BBQ's and Bikes. LA were advised undesirables wander in but nothing major.
Like I said depends where we are and may seem extreme to some but relatable to others.
As long as you can sleep at night chances are you've covered your bases
