'69 Globetrotter, Black tank for streetside bath

[dieselpup]

Hi everyone, I've been reading and researching but here is my first question about our 1969 Globetrotter. Currently the shell is off and I'm replacing crossmembers and outriggers that are rusted out. It has a street side bath with the black tank above the frame. The tank has a hole courtesy of some squirrels who lived in the trailer before we bought it. I'd like to increase the capacity of the holding tank, as well as add a gray water tank. Has anyone installed a larger black tank with the streetside bath? Or is the original 15gal large enough if replaced with a new one? Thanks in advance. -Tim

I didn`t have a black tank when I bought my 63,so I installed a 34 gal under the floor,also a 34 gal gray up in front of the axle.They hang down lower than the belly pan,so I had to make a box to enclose them.Since I will never use this trailer in cold weather I see no problem.
The 34 gals were the cheapest I could find and that is why I went that route. Dave

Here is a picture of the bath. It doesn't describe the layout very well, but the toilet is almost centered on top of the frame rail. Second picture is of the shell going up.

I'm working on a '66 'trotter. Haven't gotten to tanks yet so I'm not able to give any credible advice as of now. I'll be adding larger black + gray though so I'm very interested in what turns up here.

15 gal of 1&2 should be enough. What you really need is alot of gray capacity. I am converting a rear bath 71 21GT to a curbside wet bath and I think the tank I bought for it is only around 14gal. I am also putting in 3 11 gal tanks manifolded together for gray. As a matter of fact I just had the fittings spun on yesterday.

How big a hole is in your tank. They can be repaired.

Thanks Aerowood. The hole is approx. 1"x2" - but on closer inspection the weld is cracked out around the 3" fitting as well. Think it is too far gone? It appears the tank was supporting the toilet as the plywood was rotten on top. If the original tank has enough capacity it will save lots of aggravation.

I don't know if it's to far gone or not. Do you have a shop close by that works on these tanks? I'm lucky as I have a shop just a few miles from my house that makes tanks. Or you could try welding it yourself, many people on the Forums have done it, just not me. A new tank might even still be available. I think INCA plastics originally made your tank. Check and see it their name is on the tank along with a P/N

We checked with INCA plastics today, they still have the mold for our tank, a H7. Waiting hear back on price and lead times. The company I used to work for has a plastic welder I could possibly borrow so that is another option. (I really miss the waterjet but they don't loan it out...) Given the damage a new tank will probably be best. In truth I'm slightly ahead of myself. Need to finish up the frame first. But wanted to get tanks situated first in case i need to fit one like easyride's. So many good ideas on the Full Monte restoration too. Thanks for the link.

Fellow Streamers,
I have been following your post with interest. I have a 69/70 GT that I need to pull the bellie pans on and do some work on the holding tanks. I am interested in your retro on putting in grey water tanks. Do you know if there is room on either side of the axle to fit them and what size and plumbing config is needed?

Thanks,

The space between frame and cross members measures approximately 57 3/4" x 22 3/4" on our '69 GT. I'm guessing earlier trailers would have similar spacing but you will need to drop that belly pan to see. I'd love to see how others have plumbed their gray water tanks in. Likely as many good ways as there are tank options.
