70s Six-Pac, trying to figure out how to run new plumbing

I'm finally getting back on getting the old SixPac camper back together. Near as I can tell, it's a 1974...something. No clue what model it would have been, other than it's a full size shortbed model. This is the first one of this vintage that I've had, so I just plain don't know how things would have been done back then.

When I got it, all the plumbing had been completely removed with the exception of the sink, and a short section of hose from the sink drain to a garden hose connector on the outside. There is still some random wires under the sink, and in the forward compartment, connected to nothing. There was a hole in the countertop that I assumed was for a faucet (no faucet was installed), but for the life of me, I can't figure out where a fresh water tank would have gone, or a water pump, or any of that stuff, unless it was maybe a 5 gallon tank directly under the sink? But I think even 5 gallons might be a tight fit there. I also haven't found anything that looks like it may have a tank vent installed somewhere either in that area.

What I'm trying to figure out is how the factory would have set this up. I know I'm free to change things around (like I'll be doing when I change out the icebox for a refrigerator), but I'm still curious how it would have been set up originally.

View of sink/stove counter/cabinet


LP compartment is directly underneath the stove top


First set of unknown wires, under sink, and drain hose going outside. I cut the drain hose when I removed the sink to install a new countertop.


View from standing in the door, looking forward and right. There is a hole drilled down through the light brown wood directly underneath the lower right corner of the window, going into the lower forward compartment.


Closer look at the hole


View from door, looking in and to the left. The large hole at the front of the bench does go outside, and there is another hole under the left lower corner of the window that also goes down into the forward compartment.


Closer view of holes -


Another set of unknown wires on the left side of the forward compartment. I haven't put a meter on them yet to see if they match up with the under sink wires...as, well, that just now occurred to me to check that, lol.


I'm thinking due to the age of the camper, that there wouldn't have been a grey water tank on board, and the sink drain would have just dumped straight to outside. Perhaps the large hole near the front of the left bench would have been the original location for the water fill port, and a fill hose would have just run to the second hole there going to the forward compartment where a fresh water tank would have been? Would it have been common to not have an outside vent for the fresh water tank back then?

Though if that's the case, I'm still not sure where a hose would have gone from the tank to the faucet. There were no other holes drilled that I could see going into the cabinet where the sink is. If the tank was underneath the sink, I don't know how it would have been filled, unless there just wasn't an outside fill port back then?
  • Ahhh...removed and filled. That would make sense then. I didn't expect a grey water holding tank, after reading that it was very common on the older campers to just dump the grey water right in the ground before the environmental movement really took off.

    Probably should have looked into this a bit more before installing a regular faucet in the new counter, lol.

    So then perhaps there would have been a battery and/or power converter installed in the forward compartment where the wires are, and the two large holes there may have been for an outside electrical connection?

    I was thinking of putting a battery or two in that forward compartment, add a power converter, and fit the biggest fresh water tank I can in the remaining space to help keep weight centrally located. But now that plan is on hold as well, as I've began to seriously look at bigger flatbed trucks to more or less permanently mount the camper on (still using proper tie downs, but just having a truck dedicated to the camper) to also have more weight carrying ability to add tanks outside the camper.
  • If I remember correctly the Six Pacs sinks were plumbed to the outside where you would connect a garden hose and fill up a bucket or blueboy tank. There was no holding tank.

    For the sink there was either a manual pump type faucet or in yours probably an electric pump all in one faucet....these were used on boats and adapted to RV use. There would be a fresh water jug or tank below the sink area that could be filled from the outside on some or removed and filled on others. A very simple design and effective plus low cost to manufacture.

    A faucet similar to this

  • When I saw your title I thought you were talking about a Dodge 440 Six-Pack. :S
