It’s that time of year again. You have to endure freezing temperatures every now and then; even in South Texas. Those of you surviving off of nurse trailers in the oil patch should be preparing. After much travail, we have found the best thing to do is to fill your internal tank and bring your water hose into the house. We store ours in the shower. Most of you have little to worry about as far as frozen pipes and damage to your RV goes. I forget the mathematics, but it would take many hours of freezing temperatures before that becomes an issue. Since I admonished everyone in an earlier post, I know you all have checked and run your heaters-right? And you have checked your propane levels-right? Since we are a mobile bunch, I would be remiss if I didn't mention a few other things. The tires on your vehicles and RV’s need to be monitored. The lower the temperature goes the greater the change in your tire pressure(s). You should also allow the engines in your vehicles to warm up before putting them under load. So; get into the habit of checking a few things and be thankful we’re not in Minnesota.
