My girlfriend and I recently bought an RV. We bought a 1990 Holiday Rambler Alumalite tow trailer. It's about 27' (or about 8 meters) long. This being our first RV, we knew nothing about how to operate or care for it. We bought it with the intent to become full-time RVers and have been living in it (comfortably) for about 2 months now. One issue we ran into quickly was how to drain the tanks, after searching online I found nothing for this specific model and very little for any other, so here is my instructable for how to dump the gray and black tanks.
Step 1: Overview and Materials
I will be showing you where to find the drain valves, how to attach the hose and drain the tanks, how to clean the black tank and also some of the tools I use to do this with.
Gloves - preferably rubber or anything that won't let water or "yuck" through.
A wand - a length of cpvc pipe with a valve used to put into the toilet and rinse the tank.
The picture of the wand is easy to miss - it's next to the detergent.
Sewer hose - a special hose used to drain RV tanks.
Female to Female (not as interesting as it sounds) - a female to female garden hose adapter used to connect the hose to the wand
Laundry detergent - powdered laundry detergent (the cheaper the better) I have read on several forums that the detergent helps break apart the waste and decrease smell, and it seems to work very well.
Hand sanitizer - for sanitizing your hand as often as you need!!
I also use at our present location a portable waste tank - because there is no immediate sewer hookup available.
