Our Class B Waste Tote Storage Tray


Portable Waste Tank and Sewer Hose in the Travel Position

We really enjoy attending multiple day music festivals in our Class B.   The festivals usually last 5 to 7 days. Having our own shower and bathroom is a terrific benefit. Refilling the water tank is usually an easy task with a dolly and a water can but the waste tanks are a different story.  We usually have to chase down one of the trucks that’s servicing the portable toilets and hope they’ll make a trip our way.

As I was preparing to head out for the Floydfest music fest in July of 2022 I put together a modification to take care of this issue.

I had removed the generator on our 2017 Lexor TS back in 2018 after installing our 12V 600Ah house electric system upgrade.  I decided to use the existing generator brackets to mount a second waste hose tube and a cargo tray that swings down to allow loading.

The basket was built using the standard aluminum stock that’s available at Lowes and was assembled with aluminum rivets.   The hinges at the rear are stainless steel carriage bolts and the locks at the front are galvanized PTO pins.  I noticed the points of some self tapping screws that were coming through the floor of the area.  I trimmed those off with a Dremel and painted each one with Por15.    I also painted the edges and holes of the generator bracket that had started to rust.

We  used the basket to hold a 6 gallon waste tote.  While at the festival we used the tote to empty our black and some of the grey tank each morning (to clean the hose) and then emptied the tote in to a nearby portable toilet.  I decided to make this a daily chore due to the small size of the tote.  I did not want to take a chance that the tote wouldn’t hold the black tank contents once I pulled the valve.

The setup worked really well.  We now have the convenience of the onboard 12 gallon black water tank and the versatility of a portable cassette toilet when needed.
