Hi, I am from Australia and am doing a 2 month road trip in a rented 23'" rv with my 2 sons (19+17) to fill a 25 y.o. dream. Unfortunately this has to be done in Dec/Jan. We will pick and return the rv in Washington DC. We want to do the civil war battlefields then slowly make our way south to Florida with a run back to Washington DC in late Jan to return the rv. My problems are. 1 .How much do I have to worry about the freezing of the water/grey water/sewerage tanks as the hire company web sites mention this happening with dire and costly results,how cold does it have to get for this to happen and is it likely be that cold on my trip? 2. Is two months at this time of year too long for a my planned trip.
Thank you for taking the time to read this and for any replies thanks to you in advance.
