TANK SIZE
BASIC ADVICE FOR NEW RVERS

Hi we're thinking about buying our first RV and have found that some RVs have a bigger gray water tank than others. We're a family of 3. Could some experienced RVer tell me how important tank size is?

Hi Tom, It really depends on how you're going to use the RV. If you're going to be using RV parks always, then usually there is a hook up available to dump your tanks whenever you want, so tank size doesn't matter. You could even leave the gray tank valve open (not recommended but I sometimes do it) and everything drains away as you're using it. One reason not to do this is you usually use the contents of the gray tank to flush the line after you dump the black tank. On the other hand, if you intend to use the RV to boondock or stay somewhere where there are no hookups then the size of the tanks is very important. Very often, it is as simple as the bigger the RV the bigger the tanks. Manufacturers only have so much space available. I've found with our 32 foot RV that with 2 people showering each day and the usual water usage and toilet flushing that the tanks only last for a day, 2 at the most. If we're very careful we could maybe go three days. So whatever you do you need to find somewhere to dump tanks fairly often. Hope this helps. Ken
