In these low slung trailers, you should be concerned about ground clearance for your tank(s). For instance, if you have a drop axle, you might consider switching to a straight one in order to gain a few inches of clearance. My '60 Mobile Scout was retrofitted with a modern wide and shallow ABS black tank which runs nearly the width of the trailer. The tank has a deep flange all the way around and that flange is bolted where it intersects the forward/aft running wood members which are attached to the basic steel trailer frame for more floor support. There are about 4 bolts along the front and back of the tank's flanges. Off subject: Seems to be a good system… no smells at all since I also vented it through the roof and use a bacterial additive (no chemicals at all)… and lastly I keep the inside rinsed out thoroughly after trips. Also keeping the tank wet with some fresh water when not traveling is a good idea. I also deposit a minimum of toilet paper into the tank… I mostly discard it in a small garbage bag. On a trailer of this size, a grey tank may be superfluous. I have my shower and kitchen sink drain to the ground. Honestly, at campgrounds, no one will notice. It's no more harmful than rainwater. But… you could always carry one of those blue portable grey tanks on wheels and hook it up during the day… then loosen it's drain cap and let it slowly dribble into the ground overnight (you didn't hear that from me ).

I don't believe the above trailer had a black "tank". A Monomatic toilet would have had a tank above floor level. The waste hose attached to the end of the sewer fitting below. Trailers earlier than 1972 often did not have a grey tank.

Do you have a toilet now? Any photos? It's very difficult to help without knowing exactly what the trailer has...

Yes, it does have a toilet and a shower, but no shower head.

That appears to be an RV toilet that utilized a blank tank below. Monomatics had a larger base (the "tank").
I would do some inspecting to find out what you have. Remove the existing toilet and inspect below. If it's a tank, make sure it is open to the dump. (no crusted crud in there) In any case, the rotted white Thetford dump will need to be replaced. Great care must be taken to prevent tank damage when replacing fittings.
The first test should be running water into the tank. Let sit for 24 hours and see if there are any leaks.
Also, RV toilets flush differently than house toilets. They use a little water and have a flap (or sliding blade) to dump waste. The tank must remain "closed" with chemicals to digest solids. If the tank is left open to a sewer, solids build up and ruin the tank. (think cement build up)
I hope this helps. More modern RV sites have a lot of info on waste tanks. Most vintage trailers don't have that elaborate of a system.
