Not going to get personal here, but there are some members who just seem to lash out with sarcasm and rudeness to virtually any post to which they disagree. It almost seems like any RV'er who doesn't do things exactly like they do, is a moron worthy of contempt.
I've stayed in a few Walmart lots in my lifetime. No interesting stories to tell there. In my professional life, Walmart was a huge client, and I spent countless hours in the 142 stores in my territory. I don't think there is much crime against customers there because the risks (security cameras, witnesses, armed customers), far outweigh the potential gains. (Walmart customers are not generally the richest members of society). The exception in my experience seems to be in areas with a significant non-resident, non-documented, cash-paid labor force. These immigrants prey upon each other mercilessly, knowing they get paid in cash, and carry most of it in their wallet all the time.
One point I'd like to contribute: being 'cheap' is not the ONLY reason to try to save some money. Sure we dish out big money to buy into this game. But for some of us, unexpected repair bills, sudden medical bills, or just the increasing costs of fuel and campsites can put us into the position of having to find ways to stretch our recreation budget, or else we have to park it and sit home. I'll admit to being in that group. I enjoy my RV immensely, however my finances have not fared as well as I had anticipated when I purchased the rig. Saving money on fuel, stopping somewhere for a free night now and then, buying off-brand parts from the internet, any way I can save a buck, I'm going to do it. Don't appreciate being called cheap though. Would I like the luxury of always staying in a nicely landscaped state, Federal or privately owned campground every single night of every single trip? Sure I would! Would I want to be parked next to someone who thinks they are better than I am in every way because I spent the previous night at Walmart? No I would not.
