I welded some angle iron to the frame and then ran some across the bottom as support. I also ended up running some under the tank which isn't in the pictures. You can see what I did here.

My tanks come bellow the belly pan. Fresh water by 2" and the grey tanks by 5" I doubt I will ever have a problem...

68 Caravel - same issue

Hi Bob,

I just purchased a 68 17' Caravel and would like add a grey water tank, (as you are doing with your 18'. Any help or advise you can offer would really be appreciated. I'm not sure how to begin.

Incidentally, the aluminum belly sheet has been cut away from the area under the show, and once, a tank was installed. The previous owner took it off because it hung quite low - well below the axle. Somehow I will have to manufacture a repair of the pan to protect and seal everything. I'm not sure at all how to engineer all this - but I'm not rushing either!

Thank you!

Great info .. and?

These photos and information are really great and I'm learning a lot. I plan to install a Vintage Trailer Parts grey water tank on my '68 Caravel. The photo shows (kind of) the trailer as I bought it. Someone has installed quite a large trap and some strange, large piping. All of this will have to be removed to accomodate the new tank, and I'm not sure how things should be replaced. Is a trap even necessary?

In the photo you can see that the black water tank valve is quite a bit above the level that the outer skin would be (if the skin were still there.) Does anyone know what this should look like?

Has anyone done this work on a Caravel?

Thank you very much!

fred

It seems that every trailer is a custom job, so don't get too worried about doing yours just like someone else with a Caravel.

Your biggest challenge will be to get a tank that fits inside the frame rails and mounting it. As you mention, VTS makes such a tank, but you will need to plan out carefullly how you will plumb it so that you can tell them where to install the spun-in fittings when you order the tank. When I did mine, I actually built a model of the tank out of a sheet of styrofoam insulating sheet so that I could see exactly how it would fit, what it would interfere with, and where I needed my fittings. I would recommend this to anyone--saved me making mistakes.

The VTS tanks look an awful lot like the old Inca plastics tanks. Inca recommended that the tanks be fully supported from underneath. I have seen some threads where people install the VTS tanks just using s few metal straps going underneath the tanks, but I went with full suppport for mine. This required welding in some angle iron underneath so that I could slide in a wood panel that supports the tank.

You will need to remove, and reorganize some of the PVC/ABS piping you have under your trailer, but that is really the easy part. You will need to have a trap for your shower so that you don't smell the grey water funk in your tank (yes, it gets pretty funky). The one in your picutre looks really big, though. You can get low profile traps that will at least hang below your belly skin less. You will also need to have a vent for the tank. There may be an existing vent line from the previous owner's installation, or you may need to rig something up that ties into an existing vent.

good luck!

Here are some photos of my recent installation in my 54 flying cloud. I used expanded metal mesh for the bottom to support my tanks. I will be able to remove my tanks if necessary from underneath by removing the nuts on the threaded rods.

I will be able to snug the tanks up against the floor after I secure the floor to the frame.

The black tank on your Caravel is above the floor below the toilet. The waste value is at floor level. The handles is in the bumper. The trap is for the shower floor pan. A gray tank would have to ride below the shower pan. You can see that there is a skid to the left to protect the waste connection. Your really limited by the ground clearance in the rear section. But, up between the frame in front of the shower pan would be possible.

You could with alot of work put one behind the axle in front of the trap. Your only picking up water from the two sink drains and the shower base. A twenty gallon tank would be enough. Cut out all that crap out and get back to the 1 1/2 line that comes though the floor. Get a new 1 1/2 trap and a 1 1/2 santary tee and a 90 or two. Pipe the shower trap to the right (curb side) and pick up the 1 1/2 vanity. Get the 1 1/2 into a tank on the curb side. The tank would then drain to the street side and you would bring it around and tie it in to the four inch with some new fittings and a new 1 1/2 valve. When your there get rid of the old Thetford connection and get a modern one.

Your 1 1/2 runs from the kitchen sink to the rear it picks up the vanity and drops down to the shower base. You can see it under your vanity. The system needs gavity to work so you have to pitch the pipe down a little. This is were the problem is, you want the 1 1/2 in the top portion of the tank. The tank outlet would be at the lower end. It might work, but it would be very close.

Originally The 1 1/2 tied in below the sewer connection (Were the white cap is.) and went staight out to the ground.
