Composting toilet

[Jarrid]

Hello to all. I have a ‘68 Overlander. Typical of that model is floor rot in the aft area as well as the entry door.

I’ve just learned my black tank is leaking. It will need to be replaced. I figure if that is in need to be replaced, I might as well have all the copper plumbing replaced with PEX.

Here comes the question. Should I replace my existing toilet with a composting toilet? Would this would negate the need for a black tank? Can urine go into a grey tank?

Thank you in advance.

Our 55 never had a black tank. They just used a gopher hole. So, we went with a Nature’s Head composting toilet instead of going back with a black tank and a typical toilet. It has a reservoir for urine that is emptied after a trip. We did install a couple of 16 gallon grey tanks piped together for the sinks and shower.

That sounds like the best option.

My ‘68 did not have a gray tank. Just a black tank. It’s just forward of the rear bumper. I’m wondering if placing the two connected gray tanks near but aft of the axles would be ideal.

Thanks

I always empty the grey tanks before leaving a campsite. So, if the tanks are empty in travel, I wouldn’t think placing them aft of the axle would matter.

Hello, I've done similar things on a few 60/70'sAirstream's but I'll focus on our '68 Overlander. One of my main goals is to get as large a gray tank as I can so out comes the black tank (ours was fine) and then I source the largest tank that will fit the opening. I believe inn the '68 it is 35 gallons. This is kind of funny because the only thing that goes in it is the kitchen sink. We have basically eliminated the bathroom and in effect created a rear bedroom. The toilet we went with is a porta-potti "Curve", sleek and somewhat stylish, electric flush, fairly compact and tall enough to be comfortable. It stows in a closet for travel and when not in use. We also don't have a shower in the trailer, there is an outdoor one. So, kitchen sink, porta-potti, outdoor shower, works for us. If we need to poop in the trailer (under 5 times is 3.5 years) we use the bag method popular with van folks and treat it like dog waste. Bottom line is at some point someone has to deal with waste in some way, and we all know who that usually is. We have done multiple moths ar RV parks with this set-up. And yes, replace all that copper with pex.
Good luck, Mark D
